I've been in need to disable mass-check because it used ALL of the
memory on the machine:

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
10800 sa_train  25   5 5658m 2.9g 1144 D    0 67.6 103:19.53 mass-check

This VM is our spamgate, and has 4.5GB RAM. It used to have 3GB until
recently, then I activated mass-check and it swapped 4GB from RAM to
disk. So I increased to 4.5GB RAM, and still mass-check swaps out over
3.1GB to disk. That's just way too much RAM usage. I'm not happy to
assign a VM 3GB or more additional RAM just for mass-check, but I did
not find a switch to limit RAM usage.

We've been running mass-checks for a very long time, but it never used
so much RAM than it does now. Any chance to reduce that again?
