It is hard to reproduce in a small recipe. I've even noticed that
while the problem occurs most of the time, now and again, it works as it
should.

I didn't put it on emacs-dev initially as I wanted to be sure it wasn't
just something I misunderstood before adding to the traffic on that
list. I stated this in the original post. 

Uday has progressed things further and moved it to the dev list. He has
a better understanding of the internals of the package where we have
encountered the problem, so it is probably best left in his hands rather
than have me muddy the waters with ignorance.
