My problem is, and long time has been, the following. Every 30-40-60-120
minutes (it varies) I suddenly see CPU consumption jumps to 100% because
of tor process, so I need to stop/start it to settle things down. Also,
when I start Tor after a period of inactivity, say, a few hours or
night, I cannot start it reliably for the first time, ever. It goes up
to "Bootstrapped 95% (circuit_create): Establishing a Tor circuit" log
message and... 100% CPU. After the second start, I get 100% CPU with
50/50 probability, and after the 3rd, it finally is OK, most of the
time. Then, this 30-40-60-120 minutes cycle begins... It happens with
this "Bootstrapped 95% ..." message or a bit before that.
