Using 8K stack is probably too much. As reference, ALLOCV falls
back to heap allocation at a mere 1K. Since
bsock_recvmsg_internal is a function which will always allocate
and can trigger GC, it is in our best interest to minimize
stack usage to avoid scanning 8K of stack on GC.

As documented before, exceptions are expensive and IO::Wait*able are too
common in socket applications to be the exceptional case. Datagram
sockets deserve the same API which stream sockets are allowed with
read_nonblock and write_nonblock.
Note: this does not offer a performance advantage under optimal
conditions when both ends are equally matched in speed, but it it
does make debug output cleaner by avoiding exceptions whenever
the receiver slows down.

MSG_DONTWAIT is enough to force non-blocking I/O under Linux,
so avoid changing the state of a socket. This will allow certain
threads to do a non-destructive non-blocking "peek" while others
block (without relying on an extra ppoll syscall).
We shall be conservative about enabling this feature since some
OSes may have incomplete support for MSG_DONTWAIT. I shall
defer to a FreeBSD expert to enable that for FreeBSD.

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.
