Some things I forget to mention. zsh is supposed to be sigsuspend-ed at
the time the signal handler is executed - this maybe obvious from the
backtrace but in any case I mention it. The second thing is that I was
able to reproduce this when connected via ssh to the Cygwin machine or
when I run zsh in rxvt window but not when in Cygwin console. Maybe pty
slows things a bit and that's why the "race" surfaces in these cases.
