I've read articles about programs which use GC which have a small
working set, although it is constantly changing (I've heard of
programs allocating megabytes a second). The OS would have to swap out
the stale pages if the program's total memory use exceeds RAM, and
when the GC finally runs it will take forever and thrash swap like
there's no tomorrow.
