job control code and issig messages
From: Dave Clemans <DGC AT SDC-NET>
Locally, I have used the "job control" code from 2.8bsd, along with
header file mods from 4.1bsd to implement a system with 32 signals
and the "hold" option (value=3) to the standard signal system call.
It seems to work find, except that under moderate to heavy load
conditions, the "issig" warning message in issig(sig.c) is printed.
(i.e., issig is complaining that it found an ignored or held signal
past the point in the code where a check for those types of signals
are made and an early exit taken from the routine).
We also have gotten the message on rare occassions on our vax running 4.1.
(the vax system is straight 4.1 except for supporting RP04's and the
Versatec V80 plotter)
Has anyone (particularly anyone associated with developing the job
control code) seen this situation before?
