Shutting down the timer thread now always closes pipes to free FDs.
In fact, we close the write ends of the pipes is done in the main
RubyVM to signal the timer thread shutdown.
To effectively close pipes, we implement userspace locks via
atomics to force the pipe closing thread to wait on any signal
handlers which may be waking up.
While we're at it, improve robustness during resource exhaustion and
allow it to limp along non-fatally if restarting a timer thread
fails.

of Solaris) to avoid calling execv() which is async-signal unsafe
on Solaris 10. [Bug #11265] [ruby-dev:49089]
* process.c (exec_with_sh, proc_exec_cmd): On Solaris 10,
because ALWAYS_NEED_ENVP is 1 and envp_str is always generated,
execv() in exec_with_sh() and proc_exec_cmd() are never called.
To guarantee this, execv() is replaced by a macro to print
out error message on Solaris 10.
* process.c (proc_exec_sh): Because proc_exec_sh() may be called
by rb_proc_exec() with envp_str = Qfalse, execl() is replaced
by a macro that calls execle() with "extern char **environ"
traditional global variable on Solaris 10.
TODO: This may be unsafe and sholud be changed

RBASIC_CLASS(obj) macro which returns a class of `obj'.
This change is a part of RGENGC branch [ruby-trunk - Feature #8339].
* object.c: add new function rb_obj_reveal().
This function reveal interal (hidden) object by rb_obj_hide().
Note that do not change class before and after hiding.
Only permitted example is:
klass = RBASIC_CLASS(obj);
rb_obj_hide(obj);
....
rb_obj_reveal(obj, klass);
TODO: API design. rb_obj_reveal() should be replaced with others.
TODO: modify constified variables using cast may be harmful for
compiler's analysis and optimizaton.
Any idea to prohibt inserting RBasic::klass directly?
If rename RBasic::klass and force to use RBASIC_CLASS(obj),
then all codes such as `RBASIC(obj)->klass' will be
compilation error. Is it acceptable? (We have similar
experience at Ruby 1.9,
for example "RARRAY(ary)->ptr" to "RARRAY_PTR(ary)".
* internal.h: add some macros.
* RBASIC_CLEAR_CLASS(obj) clear RBasic::klass to make it internal
object.
* RBASIC_SET_CLASS(obj, cls) set RBasic::klass.
* RBASIC_SET_CLASS_RAW(obj, cls) same as RBASIC_SET_CLASS
without write barrier (planned).
* RCLASS_SET_SUPER(a, b) set super class of a.

_SC_GETGR_R_SIZE_MAX is available.
MirOS BSD (MirBSD 10 GENERIC#1382 i386) have getgrnam_r() but

_SC_GETPW_R_SIZE_MAX is available.
This is consistency for obj2gid.
MirOS BSD have neither getpwnam_r() nor _SC_GETPW_R_SIZE_MAX.
