[slime-devel] Slime broken on SBCL/Darwin by recent WAIT-FOR-INPUT changes

[Nikodemus Siivola]

Specifically, :OS-PROVIDES-POLL isn't on *FEATURES* there because
:OS-PROVIDES-POLL really means "OS provides poll() good enough for
SBCL's internal needs", which includes the ability to poll on things
like stdin and /dev/null -- which Darwin's poll() doesn't do.

I'm also a bit dismayed by the amount of SB-IMPL::FOO going on in
DEFUN POLL. That stuff is going to break, probably sooner than later.

So SWANK could probably use Darwin's poll() just fine -- except some
of the SBCL internals it tries to use aren't there.

Not sure what's the best solution -- and what's the most expedient one.

Cheers,
