SBCL abort is broken.

[Valera]

With sbcl 1.0.42, after
(asdf:operate 'asdf:load-op :cl-gtk2-gtk)
I can't abort execution of (sleep 10) with C-c C-c in SLIME, and with C-c in sbcl console.

1.0.39 works just fine.

Can you provide more detailed description of what happened? E.g., this happened in SLIME or in a console window; if it was SLIME, what commands were entered into REPL and which were entered in inferior-lisp buffer.

In sbcl-win32-threads, sleep (and many other things) is uninterruptible because Windows lacks UNIX/POSIX signals and threading is implemented in entirely different way.

By the way, on my machine loading cl-gtk2-gtk from SLIME's REPL hangs at some point until I enter anything into inferior-lisp.

Originally I ran into this bug when I was trying to abort execution of my server main thread from slime. But then I reproduced it in raw sbcl console just as in the first comment.
sbcl 1.0.42 Ubuntu 10.04.

The problems was that Gtk+ during initialization changes SIPIPE handler to SIGIGN and SBCL uses SIGPIPE to interrupt threads. I've commited the workaround, but this will need some more thought.

I post another issue here, because the root of the problem seems the same.
as long as on sbcl 1.1.2, timer function does not work after
(require :cl-gtk2-gtk) or (require :cl-gtk2-cairo), or both.

the package is quickloaded, so I will try the latest version after this post.

sorry it wasn't actually the case, my sbcl was loading the old version which was asdf-installed 2 yrs ago.
