[Asterisk-bsd] FreeBSD and Music on Hold -- Possible Fix

[Chris Stenton]

Ok,

Looking further into this it appears to be a threading problem. Once
this thread gets setup none of the other threads get a look in until
this thread is closed down. So for instance if you get a PSTN call in;
the zap thread does not get to run with the calling args until you start
to close down asterisk at which point the moh thread is closed.
