hmm ... (haven't done this in a while ...) I'd suggest you
periodically (once every 10', perhaps)  'pmap' all processes and see
which grow most, and then look at those in detail (perhaps using pmap
-x, or starting those with LD_PRELOAD=/usr/lib/libumem.so ...)

I'm sure other people have better ideas.
