New Revision: 184677

URL: http://svn.digium.com/svn-view/asterisk?view=rev&rev=184677
Log:
Fix a potential timer leak in bridge_softmix.

It is possible for a bridge to be created without actually being used.
In that scenario a timing file descriptor would be opened and not
closed. To fix this the timing file descriptor is now closed in the
destroy callback, not the thread function.
