When I compiled the kernel a few days ago I noticed that it took twice as
long as before, 14 minutes instead of 7 minutes. I did not have any other
processes running (I thought :-).
After some searching I finally found the problem: I started the make from
tcsh, which I installed recently. When starting the make from bash (as I did
before I had tcsh) it only takes seven minutes.
From the output of `ps' on another virtual console I noticed that the tcsh
from which I started the make was still running, using 40% CPU time!
Does anyone know *why* tcsh keeps using CPU cycles when you have started
another program from its command line? Bash doesn't have this behaviour.
(I tested this with 0.97.2 (mcc) and 0.97.5; the tcsh I use is compiled from
the original sources an a patch posted on comp.os.linux on August 24 by Jay
Berkenbilt).
