It looks like the fix above introduces regressions (actually other new
bugs):

libmultipath: update waiter handling
The current 'waiter' structure accesses fields which belong
to the main 'mpp' structure, which has a totally different
lifetime. With this patch most of these dependencies are
removed and the 'waiter' structure can run independently
of the main 'mpp' structure, reducing the risk of
use-after-free faults.

Race condition when calling stop_waiter_thread()
We cannot access the waiter structure from other threads as
the lifetime is totally different and it might be deleted
at any time.
So we better store the pthread id in the calling thread and
just send a signal to the thread.
