Specified by the following environment variaables:
- RUBY_THREAD_VM_STACK_SIZE: vm stack size used at thread creation.
default: 128KB (32bit CPU) or 256KB (64bit CPU).
- RUBY_THREAD_MACHINE_STACK_SIZE: machine stack size used at thread
creation. default: 512KB or 1024KB.
- RUBY_FIBER_VM_STACK_SIZE: vm stack size used at fiber creation.
default: 64KB or 128KB.
- RUBY_FIBER_MACHINE_STACK_SIZE: machine stack size used at fiber
creation. default: 256KB or 256KB.
This values are specified at launched timing. You can not change
these values at running time.
Environ variables are only *hints* because:
- They are aligned to 4KB.
- They have minimum values (depend on OSs).
- Machine stack settings are ignored by some OSs.
Default values especially fiber stack sizes are increased.
This change affect Fiber's behavior:
(1) You can run more complex program on a Fiber.
(2) You can not make many (thousands) Fibers because of
lack of address space (on 32bit CPU).
If (2) bothers you,
(a) Use 64bit CPU with big memory, or
(b) Specify RUBY_FIBER_(VM|MACHINE)_STACK_SIZE correctly.
You need to choose correct stack size carefully. These values
are completely rely on systems (OS/compiler and so on).

RB_RESERVED_FD_P): added. This C API is to limit to access
fds which are used by RubyVM internal. In this version of
CRuby, return 1 if fd is communication pipe.
If your application needs to close all file descriptors to
preent resource leak, skip internal fds using this C API.
We also define a macro RB_RESERVED_FD_P(fd). So you can write
#ifndef RB_RESERVED_FD_P
#define RB_RESERVED_FD_P(fd) 0
#endif
for Ruby 1.9.2 or previous version to write compatible extensions.
See [ruby-core:37727]
* thread_win32.c (rb_reserved_fd_p): added (return 0 for any fds).
* io.c (rb_io_initialize): raise ArgumentError if given fd is reserved by Ruby.

we need to add stack size for getting stack start address.
And, we don't have to decrease guard size twice.

stack start guess if native_thread_init_stack() can be used.

no waiting thread. If there are 2 or more runnable threads,
the timer thread does polling. Avoid polling makes power save
for several computers (0.2W per a Ruby process, when I measured).
If outside-event such as signal or Thread#kill was occuerred
when the timer thread does not do polling, then wake-up
the timer thread using communication-pipe (the timer thread
waits this communication-pipe with select(2)).
