Hi,

cvsup at Wed Mar 22 04:03:28 GMT 2000, this built without problems with -j8
on my SMP box, but on a uniprocessor (-j4, eveything else the same)
something appears to have deadlocked. The machine is generally OK but the
build has hung and there are 57 cron processes hanging around (ps ax
follows). Any ideas? I'll keep it hanging around for a bit, let me know if
you want more info.
