I'm not sure how to force a manual GC.  I'd be happy to test it out if
you can tell me how.

Looking at the memory usage graphs across all of these particular
instances, I can see that *some* things are getting GC'd, but usage
generally remains flat at a particular point throughout the day (eg,
it's currently sitting at 25% utilization on one system -- or about
1.2G -- and I can see that memory usage rises to 1.5G at certain
points, but then goes back down to 1.2G ... when we're at 1.2G,
there's basically nothing in the handful of queues and they are
effectively idle).
