The Delay(0) bug is timing dependent (no surprise there...).  Basically,
it loses time from the previous request on the list: sometimes all
of it.

A continuous loop of Delay(0)'s and a continous loop of trackdisk
operations will trash disks about on in 147,000 delays.  This is
about 3 minutes of wall clock time, when both the disk is
continuously busy and there is an endless supply of Delay(0)'s.
I have no doubt that some peoples systems will fail more often, but
that's what my tests showed.  The problem manifests itself by the
trackdisk not waiting the proper amount of time while writing a
track.

Once again, this is fixed in 1.4.  We're exploring ways to
release a patch before that, but until we figure it out,
the official line is "wait for 1.4".
