It crashed because the SIGALRM handler, which should be called in
the main thread, was actually called in a non-main thread. This
bug was already fixed in May in CVS, the EMACS_22_BASE branch.
As it was fixed after the Emacs 22.2 release, you cannot solve it
by simply upgrading your 22.1 to 22.2. Alternatively, you can
apply the corresponding patches to the Emacs 22.2 source tree.
