 Hi Rob,

 Thanks for your suggestions.  I should have been a bit more verbose
 in my platform description -- I'm using 64-bit instances, which I think
 in a Ben Black video I saw led to a sensible default usage of mmap
 when left at auto.  Should I look at forcing this setting?

 I'm using 0.6.5 - the ones bundled by Eric Evans <>

 Because these are 32GB machines, I've not configured them with
 any swap at all.  I've rarely done this in the past - but was aware
 there was this swap-hell scenario with JVM's, and the rationale
 makes sense -- it's better to have the JVM crash ''cleanly" than
 to have it grind the machine to a halt and make it impossible
 to get onto the machine to kill the process.
