Hello,
AH>FWIW, here is a patch to alloc.c which fixed the problem for our
AH>installation; all it does is install a SIGCHLD handler right before the
AH>sleep(3), and now that the signal is being paid attention to, the signal
AH>pops us out of the sleep(). We then re-install any previous SIGCHLD
AH>handler.
JJ>Patch?
Egads! I must've been on shrooms. Here it is:
