I have just tried running Bernd Schmidt's make -j script on a clean
1.3.88 and 1.3.88 with the above patch. The clean 1.3.88 fails with the
odd SIG11 and SIG6 but the patched version is perfect. Excellent work!!

(I've tagged a copy of Bernd's script on below for those linux-kernel
people who missed it the first time around and want to stress their
machines a little. On the subject of SIG11: the memtest program on sunsite
does an excellent job of sniffing out bad RAM and even found a buggy
motherboard for me which kept gettting SIG11's)

PS. Don't expect to get any useful work done while this script runs. Also
I have 16M RAM and used about 20M swap space during this test. Had a load
average of 64 for a while too!
