I've seen yum eat up to around 200 MB memory.

Amazingly the system is still running.  I'm resizing both of the
VMs by up to half their maximum size every second, which seems to
interact "quite poorly"[1] with the VM.  I'm currently wondering
whether to find a way to improve this, or whether it's just a
"doctor, it hurts" thing.
