The problem is with `run-at-time' on XEmacs. Please see my bug report¹
posted to the xemacs-beta mailing list.

Until there's a change to `run-at-time' or `start-itimer' on XEmacs,
we can work around the problem by substituting the 0 in the
`run-at-time' call above with `itimer-short-interval'.

I noticed that there are a few places in SLIME that use `run-at-time'
with a expiration of 0 that should be subject to similar failure, but
the debugger hang described in this thread is the only problem I've
experienced so far.
