I may have misunderstood in my previous reply.  You said "chunked"
automatically.  I somehow misread "discarded" automatically (when too
big), which is what is going to happen after the release.

Richard rejected _automatic_ adding of undo-boundaries for timers when
we discussed this earlier.  Note that all timers, not just idle
timers, have caused problems in this respect (which were fixed on a
case by case basis).  We never looked at processes, although the
problem can occur for them too.
