Read my other posting.  The only possible errors in this particular
read case are related to inpout redirection from a file (EIO).  If
the read returns a zero, it only does so because SIGHUP processing
has not killed the process as it should have in the trampoline code
on the way out of the read system call before the call was alloed to
return.
