 Hi,

 From a couples weeks, Tor is using 100% of one core from my 4 .

 I running kubuntu Lucid 10.04.1 x86 64 ( 4 cores ), relay non-exit ,

 So it start with core "1" at 100 % a few time after the use the "2" at
 100% a few time and the "3" ect..   Early it never does that, so it must
 be appear quite recently.

 Tor: commit 4dbd8ba008de7eea623e3b760a6c43040d145a8d
 libevent: commit f13e449b531bb14d076e28660e2d33fb6fb255ab
