This backport of r58812 is necessary to ease backporting r59028,
which fixes a real bug.
* thread.c (struct waiting_fd): declare
(rb_thread_io_blocking_region): use on-stack list waiter
(rb_notify_fd_close): walk vm->waiting_fds instead
(call_without_gvl): remove old field setting
(th_init): ditto
[Feature #9632]
* vm_core.h (typedef struct rb_vm_struct): add waiting_fds list
* (typedef struct rb_thread_struct): remove waiting_fd field
(rb_vm_living_threads_init): initialize waiting_fds list
This should fix bad interactions with test_race_gets_and_close
in test/ruby/test_io.rb since we ensure rb_notify_fd_close
continues returning the busy flag after enqueuing the interrupt.
* thread.c (rb_notify_fd_close): do not enqueue multiple interrupts
[ruby-core:81581] [Bug #13632]
* test/ruby/test_io.rb (test_single_exception_on_close):
new test based on script from Nikolay
