My, how times have changed.
Here, I come from the Lisp world where PDP-10s had magnetic core memory, and a max of 1MiB (of 9 bit bytes) in address space. Lisp Machines used DRAM, but at least early on less than an address space (64MiB of 8 bit bytes), and keeping your working set inside that was an issue if for no other reason than GC by the time I showed up was incremental copying without generations (i.e. an increment of GC would tend to trigger a page fault).
So I assure people like sovande that this can be done correctly, even if it's convenient to "ship it now!" and later find out what's "leaking" (keeping unneeded stuff from the tender mercies of the garbage collector).
