 This is somehow reproductible, though I got slightly different stack
 traces
 each time.
 But it always bombs in `connection_commit`, though.

 Configuration:
  * tracd on Linux
  * python 2.3.4
  * pysqlite 2.0.4 with sqlite 3.2.7.

 With older versions of pysqlite, I got simply dead-locks, but this was
 not a good thing either...

 Here's the stack trace:
