Hum... mono hanging... I experience this with Banshee this is why it s
marked IGNORE:
http://www.freshports.org/multimedia/banshee/

I used to see the mono process in the "STOP" state, but last time I
tried it was in the "umtx" state.  Requesting a backtrace from mono make
it abort, attaching gdb to it also fails.  The problem happenning after
a random amount of time (a few minutes, a few hours) I have not been
able de localise the source of the problem yet.  If you have
experiencing the same problem but can reproduce it, it's a HUGE step
forward!  Can you please provide me a minimal working example ?  I tried
to jack something but it works as expected :-/
