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.

  enough time to wait. It depend on kernel behavior. And,

  is true, it doesn't wait at all and Process.kill() users don't
  expect threading changes Process.kill() behavior. [Bug #7560]

shyouhei 2c770d676c * signal.c (rb_atomic_t): GCC (of at least recent versions)
has  ubiquitos  support  for  atomic  operations.   On  that
  compiler a C  program can isse a memory  barrier using these
  dedicated  instructions.  According to  the GCC  manual they
  cargo culted  this feature form  the Itanium ABI  so chances
  are that  other compilers  could also support  this feature.
  But so far GCC is the  only compiler that I know to have it.
  Also note that this works on non-Itanium machines.
