I still see some compiler warnings from this:

tqueue.c: In function ‘tqueueReceiveSlot’:
tqueue.c:124:18: warning: variable ‘tup’ set but not used
[-Wunused-but-set-variable]
tqueue.c: In function ‘TupleQueueRemapTuple’:
tqueue.c:612:7: warning: variable ‘dirty’ set but not used
[-Wunused-but-set-variable]
