Fix deadlocks in GC on Windows.

When multiple threads cons and end up in the GC, they could deadlock
trying to send messages using safepoints and trying to acquire the
*already-in-gc* lock.

Also happens to stop gc.impure.lisp / BUG-936304 test from failing on linux-x86.

Thanks to Paul Khuong for the patch.
