+1. MacPython still has Mac/mwerks/malloc as an optional private 
malloc (not used normally, it used to be much speedier than the 
platform malloc, but that one got better all the time) and it is 
almost identical in feature set to what Tim described.

It would be so nice if this were a standard feature. For 
instance, I never realized that Windows malloc could do all the 
tricks I've always used my private malloc for.
