Thanks.  It had been something of a shot in the dark.  As John pointed
out if the processors are going "zombie" on us for this long it's
not a good sign to begin with, and not all cases will be fixed by just
waiting longer.

Marius's interrupt work looked much much more promising, at least
what little I was able to understand from it. :-)
