After about 3-1/2 hours of successfully running 3 seperate make -j4
kernel compiles (two of them on nfs mounts) on my 32Meg K6, I killed
off the compiles and did a ps aux --- it hung -- I did another --
ditto. I found out the pid's using the magic sys-req and tried to
kill them -- no soap -- "kill -9" ditto. Here is the edited contents
of my log after shift/alt/control magic sys-reqs.

etc -- response good so it is not apparently hurting the kernel.
