[users at bb.net] RAM consumption of twisted for buildbot 0.8.12?

[Dan Kegel]

15 days of uptime, about 1450 builders, and twisted is using 1.7GB of
*physical* ram.

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
 1196 buildbot  20   0 3124m 1.7g 4456 S   10 14.8   1515:22 twistd

Aw, what the heck, RAM is cheap these days... still, it's a bit surprising.
