 Replying to [comment:20 karsten]:
 > I'm afraid I can only speculate about the problem.  I only saw one part
 in the code that uses libevent, and that's in `retry_utp_listener` in
 `src/or/connection.c` where we listen for new incoming connections.  I
 also think I found the place where we send out bytes to the network using
 `sendto` in `tor_UTPSendToProc` in `src/or/channeltls.c`.  But I didn't
 find where we're informed about new incoming bytes from existing
 connections.  Maybe this happens in a place that is not intercepted by
 Shadow?

 Correction: `utp_read_callback` isn't only called for new incoming
 connections, but also for new incoming bytes on existing connections.
 AFAIK.
