 The default value for MaxMemInQueues is 8 GB, which means that for many
 users, there simply won't be any support for OOM prevention.

 I think we can do better than that by detecting the physical memory and
 picking a default MaxMemInQueues based on a percentage of that.  Of
 course, the user should still be able to override that value.
