documents
online that cover this in detail ?. It would be good to glean a
view of the
tricks and techniques people have come up with on RB on this issue

To be honest, I can't remember another situation except for trees

A self-cleaning file cache is another a useful case.
Managers for persistent objects -- you don't want two copies of the
same object in existence, but you also don't want to eventually hold
an entire table in RAM. I use this quite a bit.
