They're stuck waiting for another CM event, right?  And presumably no
more events occur after IB_CM_TIMEWAIT_EXIT for a connection that dies.
So I guess your application should have the thread terminate after it
knows that the connection is done.

What's wrong with pthread_kill()?  That seems like another perfectly
valid solution -- ib_cm_get_event() is basically doing a read(), so a
signal would wake up the read() and make the function return.
