I think the code is pretty simple to read:

https://github.com/racket/web-server/blob/master/web-server-lib/web-server/managers/lru.rkt#L42

It just uses current-memory-use, which looks at the entire VM's memory
usage. It is conceivable to grab the servlet's custodian and look at
just the cost of the servlet, but unless there are many servlets, that
will basically be the same value.
