Summary:                    Hangup extension executed twice in 1.6.2 RC2
Description: 
When a user hangs up a call, in certain circumstances, the hangup extension
can end up being executed twice.

If I comment out this section of my dialplan, the hangup extension is only
executed once:

exten => _X.,n,Goto(s-${DIALSTATUS})

exten => s-CONGESTION,1,Congestion(5)
exten => s-BUSY,1,Busy(5)
exten => s-.,1,Congestion(5)

Otherwise, the hangup extension is executed twice.  The odd thing is that
the console output does not display that the code above is being executed.

---------------------------------------------------------------------- 
I can confirm this on SVN trunk as well. The interesting thing is, if I
comment out the following while loop in pbx.c(line 4777 or so):

	while ((res = ast_spawn_extension(c, c->context, c->exten, c->priority,
c->cid.cid_num, &found, 1)) == 0) {
			c->priority++;
		}

the h extension works as expected. A cursory look at the code looks like
the h extension would never get executed if that code is missing...
