Brain cramp ... but it's 4AM. Not KBytes. MBytes. Those numbers are
already in KBytes. We're losing 8.5 to 9 megabytes per 2050 1K messages.
And I can now report the following results before calling it a night:
./postal -m 5000 -p 1 -c 1000 amitower userlist - | tee -a test.log

That was a quick 6 minute test with large messages, a single connection, and
relatively few messages. We are losing 4K to 8K per 30 second check, so
between 8K and 16K per 10 5000 KByte messages (I attribute the initial
larger loss to the requisite memory buffer required to hold storage). And
yes, this time I do mean KBytes, not MBytes. :-)
The JIT for that test was Hotspot Client.
