     The only problem I have with that is the clock jump bug.  I finally did
figure out where to find a copy of 0.2.0.20-rc to download.  I ran it for
about a week until my system crashed last night.  During that time, the clock
jump message appeared only once, about two days into the run.  So I suspect
that the bug was introduced between 0.2.0.19-alpha and 0.2.0.20-rc.  However,
since the later releases all issue that message considerably more often, I
now wonder whether more than one change was made in different releases, but
resulting in the same external symptoms.  As long as it doesn't start doing
it more often, I'll stick with 0.2.0.20-rc for now.  0.2.0.21-rc through
0.2.0.25-rc are all unusable for servers as far as I'm concerned.  Unless
someone has identified the cause of and fixed this bug in 0.2.0.26-rc, I
think I should assume that it would be yet another waste of time to try it
out.
