Thanks for the diagnosis.  I installed trunk bzr 117201 to try to fix 
this problem.  I don't see how this would explain the bug in emacs-24, 
though, as in emacs-24 the signal handler invokes pthread_sigmask 
(SIG_SETMASK, &empty_mask, 0) before calling quit_throw_to_read_char, 
and the pthread_sigmask call should restore the signal mask.
