Yes, it is running on a linode and the OOM eventually kills the process.
There is some swap space available, but I probably should increase it. I
started with trying to understand my racket program because it is a lot
more fun for me than sysadmin type stuff :)

Is this a cloud server? Is the problem that the "out-of-memory" (OOM)
handler is killing processes? That

releases a page at the beginning of a major GC only if the page was
unused at the *start* of the previous GC.

Thanks for the response as it confirms my suspicions. For my purposes the
resident memory reported by top should be accurate enough. I'm talking
about 100s of MB that I'd like to free immediately, so I'm not too
concerned about CODE pages or the GC taking a few MBs. All that is dwarfed
