 I patched the 0.4.2.5 Tor sources here at this Gentoo Linux system and
 restartet both Tor relays.
 I observed a jump of the value "cswch/s (Total number of context switches
 per second.)" - collected by sysstat - from 10,000 to 20,000 at this
 system. I do wonder if this is due to the debug code or completely
 unrelated?
