* libguile/finalizers.c (queue_finalizer_async): We can allocate, so
just use scm_system_async_mark_for_thread instead of the set-cdr!
shenanigans.
* libguile/scmsigs.c (take_signal):
* libguile/gc.c (queue_after_gc_hook): Adapt to new asyncs mechanism.
Can't allocate but we're just manipulating the current thread when no
other threads are running so we should be good.

business.

| Ludovic Courtès | 2009-08-19 | 1 | -28/+2 |
| * | Remove AC_SYS_RESTARTABLE_SYSCALLS and related code...As the Autoconf documentation says, "These days portable programs
[...] should not rely on `HAVE_RESTARTABLE_SYSCALLS', since nowadays
whether a system call is restartable is a dynamic issue, not a
configuration-time issue."
In other words, if we ever rely on HAVE_RESTARTABLE_SYSCALLS, we are
at the mercy of any code that Guile happens to be linked with, because
that code could install a signal handler without the SA_RESTART flag,
and then a Guile system call could unexpectedly return EINTR.
The readline part of this goes back to this problem report:
http://sources.redhat.com/ml/guile/2000-05/msg00177.html; and is an
excellent example of the above paragraph. It was noted during the
discussion that undefining HAVE_RESTARTABLE_SYSCALLS would fix the
problem, but that solution wasn't adopted - I guess because Guile was
still using cooperative threads then (not pthreads) and so there was a
significant concern (whether founded or not) that not using
restartable syscalls (where available) could lead to a loss of
performance.
Now Guile's default mode of operation is with pthreads, where we
already don't assume that HAVE_RESTARTABLE_SYSCALLS is reliable, so
there is no possible further performance loss. And in any case we
really have no choice, if we want correct operation.
Thanks to Sylvain Beucler for reporting this and suggesting the fix.
