23.0.50; accept-process-output on OSX

[Markus Triska]

Evaluating the form:

   (let ((p (start-process "p" (current-buffer) "bash")))
     (accept-process-output p)
     (kill-process p))

should yield inserted text similar to:

   host:~ user$ 
   Process p killed

However, with latest CVS on OSX 10.4.10 (NOT using the deprecated Carbon
port, but X only), the cursor turns to "waiting" and Emacs is blocked
until I press C-g. A version based on the Unicode2-branch from September
(i.e., before multi-tty was merged) works correctly. From git bisect on
the git repository, I can confirm that the problem is between commits

   14e35740aab7e3532973e37aa7fc52ea5b1b5008 (good)   and
   88a3d732392da6e0d9f333c373de3a53b3d9f080 (bad)

Between those, Emacs does not compile on my platform. After configuring
with the flags found below, I installed Emacs with:

   $ export LIBS=-lresolv; make bootstrap; sudo make install

After M-x toggle-debug-on-quit and quitting with C-g, I get:

   Debugger entered--Lisp error: (quit)
     accept-process-output(#<process p<1>>)
     (let ((p ...)) (accept-process-output p) (kill-process p))
     eval((let ((p ...)) (accept-process-output p) (kill-process p)))
     eval-last-sexp-1(nil)
     eval-last-sexp(nil)
     call-interactively(eval-last-sexp)

Thanks.
