Ok, here's what I've got so far.
Pulling the SECOND delta both gets rid of the stability problem AND the
requeue fix (e.g. getting rid of that denies the essential purpose of the
deltas in the first place.)
Removing the FIRST delta, which is:
218a219,221
if (!dumping)
callout_r
Nevermind on my update - somehow "cvs" got the wrong tag (5.3-RELEASE) on my
sandbox build.
Doing it again :)

Without the last delta the requeue doesn't happen at all.
So you're saying that this change:
1.42: When resubmitting a timed out request, reset donecount.
produces the problem?

Pretty sure its the requeue (e.g. 1.40 and 1.42).
Isolate the specific change please.
