test/ruby/test_exception.rb on Windows.
wrap by __try and __exception statements on mswin to raise SIGSEGV
when EXCEPTION_STACK_OVERFLOW is occurred, because MSVCRT doesn't
handle the exception.
however, (1) mingw-gcc doesn't support __try and __exception
statements, and (2) we cannot retry SystemStackError after this
change yet (maybe crashed) because SEH and longjmp() are too
uncongenial.
* signal.c (check_stack_overflow, CHECK_STACK_OVERFLOW): now defined on
Windows, too.
* thread_win32.c (ruby_stack_overflowed_p): ditto.

from Thread.async_interrupted? to Thread.pending_interrupt?.
Also rename option from `defer' to `never'.
[ruby-core:51074] [ruby-trunk - Feature #6762]
* vm_core.c, thread.c: rename functions and data structure
`async_errinfo' to `pending_interrupt'.
* thread.c: add global variables sym_immediate, sym_on_blocking and
sym_never.
* cont.c, process.c, vm.c, signal.c: ditto.

sigsegv handler. enlarge value when x86 or x86_64 on Linux.
Linux has very small MINSIGSTKSZ size (2048 bytes) and
our sigsegv routine need 5KiB at least. [Bug #7141]

has no good effect and makes meaningless 100ms delay. 1)
when sending signal to another process, waiting has just silly.
2) when sending signal to current process, 100ms is often not
enough time to wait. It depend on kernel behavior. And,
rb_thread_polling() doesn't make sense anyway. When rb_thread_alone()
is true, it doesn't wait at all and Process.kill() users don't
expect threading changes Process.kill() behavior. [Bug #7560]
