Follow-up Comment #4:

>From what I could see in the video, the memory usage inside Octave was low
(last line of whos gives the bytes used), so I'm inclined to close this as
invalid / not an Octave bug.

Most probably, because your system has 64 GB, Linux is slow to give up cached
RAM because it figures the cache might as well hang around unless something
else needs to really use that memory. If you're bothered by it, look up
swappiness, but I've never needed to touch that kernel parameter, and if
you're new to OS settings you shouldn't touch it for a while, at least not
without reading up on it.

Even if it looks like the memory isn't being returned, if you need to use
another program while Octave is running, Linux will allocate that memory to
the other program on demand.

I'll close this as not an Octave bug / normal Linux behavior. If Octave
misbehaves comment here and we can reopen it.
