Comment:

 Hm.  So there are at least 2 issues here.  One is CPU usage, one is bad
 balancing.

 Bad crypto load-balancing is a known bug that we're trying to fix during
 0.2.3.x series; #1749 is the main ticket for that.

 But it's also possible that we're doing something dumb that pegs one of
 the CPUs.

 If you (or anybody) has a chance, it would be good to get oprofile numbers
 out of a relatively busy Linux server just to see whether we're wasting
 time somewhere crazy.

 I'm putting this in the "unspecified" milestone for now, pending profile
 results.  If they look reasonable, we should close this as a duplicate of
 #1749.  If there's something stupid going on, we should reassign this bug,
 and fix it in 0.2.2 or 0.2.3.
