The issue here is that a search exceeding sizelimit, if not cached,
would destroy cacheability of all searches contained in it.  Since a
search that could exceed sizelimit is likely to include substrings or
so, things like (mail=*domain.com) exceeding sizelimit would make all
searches for (mail=foo@domain.com) non cacheable.  I fear there's little
to do about this, unless we want to heavily rework query containment
stuff (and I don't feel like, as I'm having hard times in understanding
what that code does).  So I have now a bottomline fix that handles
sizelimit correctly, but makes all cacheable queries contained in the
offending one no longer answerable.
