Looking at eval.c, it seems that the perl's wait() ignores certain
signals. I don't think this is correct behavior.

I have an application where I want to spawn a subprocess (which
setpgrp()'s and goes about its merry way) and at the same time I want
the parent to wait() for the child to finish. Now, if I want to
interrupt the parent, I should be able to (without killing the child,
so system() will not do).

Is there anything wrong with commenting out the signal(SIGINT, SIG_IGN) 
and the other SIG_IGN line in the O_WAIT case in eval.c??

Why are they there in the first place?
