I'm sure the folks at bioc-central will recall exactly how
multiple=TRUE does, but some of us have a harder time remembering the
ins/outs of the findOverlaps internals but would still like to try to
help ;-)

Could you maybe provide a small example (few ranges in the query, a
few in the subject) that would result in a findOverlaps() call w/
multiple overlaps and show us what you'd like to get out of it so that
your scripts can keep humming?

Thanks,
