merge revision(s) 26371,26373,26374,26972:
* eval.c (thread_timer, rb_thread_stop_timer): check the timing of
stopping timer. patch from KOSAKI Motohiro <kosaki.motohiro _AT_
jp.fujitsu.com>
* eval.c (rb_thread_start_timer): NetBSD5 seems to be hung when calling
pthread_create() from pthread_atfork()'s parent handler.
* io.c (pipe_open): workaround for NetBSD5. stop timer thread before
fork(), and start it if needed.
* process.c (rb_f_fork, rb_f_system): ditto.
fixed [ruby-dev:40074]
jp.fujitsu.com> via IRC.
fork(), and restart it after fork() on parent, and on child if
needed.
these changes are tested by naruse. fixed [ruby-dev:40074]
* io.c, eval.c, process.c: add linux to r26371's condition.
