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.

This saves a system call by allowing us to use SOCK_NONBLOCK in
Linux when accept4 is available.
Note: I do not agree accept_nonblock should always make accepted
sockets non-blocking, and will propose a future API to allow
controlling whether accepted sockets are non-blocking or not
regardless of how they were created.

This is analogous to functionality found in IO#read_nonblock and
IO#wait_nonblock. Raising exceptions for common failures on
non-blocking servers is expensive and makes $DEBUG too noisy.

* ext/socket/init.c (rsock_connect): refactor for blocking
(wait_connectable): clear error before wait
[Bug #9356]
We no longer use non-blocking sockets to emulate blocking behavior,
so eliminate error-prone and confusing platform-dependent code.
According to POSIX, connect() only needs to be called once in the
face of EINTR, so do not loop on it.
Before waiting on connect, drop any pending errors, since
rb_wait_for_single_fd may not clear the existing error
properly.

writable to avoid infinite loops on FreeBSD and other platforms
which conforms to SUSv3. This problem cannot be reproduced with
loopback interfaces, so it's hard to write test code.
rsock_connect() and wait_connectable() are overly complicated, so
they should be refactored, but I commit this fix as a workaround
for the release of Ruby 1.9.3 scheduled on Feb 24.

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.
