Since r62466 ("thread_pthread.c: shorten and fix thread cache implementation"),
our thread cache is no longer buggy with programs using fork.
This makes significant improvements in vm_thread_alive_check1
and vm_thread_create_join benchmarks and does not introduce
regressions.
Unlike old thread cache, I've changed the cache to only last 3
seconds since per-thread setup in most programs rarely takes
more than a few milliseconds to re-establish things like network
connections. This is configurable by changing the THREAD_CACHE_TIME
variable.
I hope this allows users to simplify their code by removing the
need for thread pools in many cases.

* ext/pty/pty.c: Check whether each STREAMS module is already pushed
or not by using I_FIND ioctl call, before pushing it by using I_PUSH.
Solved test failure on Solaris. On a Solaris 10 machine, ioctl I_PUSH
"ldterm" twice was the cause of duplicated "\r".

* vm_core.h (VM_ENV_DATA_INDEX_ENV_PROC): ep[VM_ENV_DATA_INDEX_ENV_PROC] is
allocated to mark a Proc which is created from iseq block.
However, `lep[0]` keeps Proc object itself as a block handler (Proc).
So we don't need to keep it.
* vm_core.h (VM_ENV_PROCVAL): ditto.
* vm.c (vm_make_env_each): do not need to keep blockprocval as special value.
* vm.c (vm_block_handler_escape): simply return Proc value.
* proc.c (proc_new): we don't need to check Env because a Proc type block
handler is a Proc object itself.

IMHO, this increases readability, too, since it's not
immediately clear that the object is on the malloc heap
and not a regular Ruby object.

atomic_sub_nounderflow is expensive and objspace_malloc_increase
was showing up near the top of some `perf` profiles. The new
implementation allows the compiler to inline and eliminate
some branches from objspace_malloc_increase.
Furthermore, we do not need atomics for oldmalloc_increase
This consistently improves bm_so_count_words benchmark by
around 10% on my hardware.

We must not leak EINTR to users in case a signal hits a
ppoll/select caller right when (or just before) the timeout
expires. In other words, the timeout should take precedence
over the -1 result from ppoll or select.
We also try one more time in case of EINTR with a zero timeout,
since technically the syscall finished before timing out if
it returns EINTR.
Regression appeared in r62457
("thread.c (update_timespec): use timespec_update_expire",
commit e6bf0128add103730d8c96727f3ed4dab95088e4)

for now, which was committed in r63333.
Currently trunk's JIT seems to have some wrong behaviors, and this is
the most suspicious culprit of them for now. In the future, I may have
a strict test environment to detect the cause, but there's no enough
time to test this until preview2. So let me revert this and see how it
goes after this.

URI::Generic: Respect no_proxy for both parent domain and
subdomains It is now possible to add just the subdomains for proxy bypass. In
a setting where the main domain needs to go through proxy while the
subdomains don't, it is now possible to just add the subdomains to the
no_proxy list.
The assumption that subdomains and the parent domain should
behave the same wrt no_proxy has been removed.
eg: Adding .example.com in no_proxy would allow example.com
to go through the proxy.
