rb_fd_init() uses malloc() to create fdsets instead of traditional stack
allocation. This also requires using rb_fd_term() to free() memory, so
rb_ensure() must be used[1]. Often this is for waiting on a single fd,
so the rb_io_poll_fd() interface is better for extension authors all
around even if it internally uses select().
As for poll() support, Evan Phoenix pointed out poll() doesn't work on
OS X with ttys/pipes (ref: [ruby-core:35529]). I don't know about other
kernels. Ideally, poll() should work everywhere select() does (and
select() should be deprecated). I would like to encourage other OSes to
get where Linux is (or get more people using Linux :).
On a related note:
Ruby also still needlessly checks for read/writability with select()[2]
even though though we have support for blocking regions. I think
that is safe to remove if we check return values with
rb_io_wait_{read,writ}able(). One part of
http://redmine.ruby-lang.org/issues/4535 does exactly this but I have
another patch to kill more unnecessary select() calls that aren't
bugs, just extra code/syscalls.
[1] though from reading through do_select() in thread.c, I don't think
do_select() can raise..
[2] via rb_thread_wait_fd()/rb_thread_fd_writable()
