Comment:

 Thanks.

 Threads 27 and 28 are the main issue here.
 StopActiveScan() in 28 is being run from within the event loop, but thread
 27 was already in SetChannel() and is waiting for the event loop to get to
 the end of the loop. StopActiveScan() is waiting for SetChannel() to
 complete, hence the deadlock.

 Threads 2, 4, 9, 12, 23 and 24 are also blocked on waiting for thread 9
 streamhandler.cpp:159, but I'm treating this as a red herring for now.
