Summary:                    race condition in res/timing_* interfaces
Description: 
While doing some testing with trunk it seems I hit a race condition where
ast_timer_open() is being called and handled by the DAHDI timing interface,
but then before ast_timer_ack gets called, another timing interface gets
registered and when ast_timer_ack gets called the timerfd interface handles
the call and the file descriptor is therefore not valid for that module (in
this case the resulting error is invalid argument.
