I'm afraid there were significant changes in process control between
Emacs 21 and 22. I don't know any Emacs developers who use Tru64 Unix,
and the bug doesn't seem to occur on GNU/Linux. Would it be possible
for you to try to debug this? Does the hang occur at the call to
setpgrp() in callproc.c, as indicated by the backtrace you sent? There
are several different versions of the call to setpgrp for different
platforms; which one does Tru64 Unix use?
