Since no answers have been forthcoming, I'm going to assume that there
is no one-step way to do this at present.  In which case...

The function I'm envisaging is essentially:

ets:select_delete(Tab, MatchSpec, Limit) -> NumDeleted

which behaves identically to ets:select_delete/2, but deletes a maximum
of Limit items.  I guess an analogous function should probably be added
for dets as well.

Cheers,
