[racket] Profiling memory use

Makes sense.

So -- correct me if I'm wrong ;-) -- my main choices are to use a Custodian
to impose a hard memory limit, and/or throw in tactical
 (collect-garbage)'s to help keep usage down.

In terms of profiling where the memory is going, are there any sharper
tools than (current-memory-in-use)?


Thanks again

Dan
