I don't think the current fix is complete. Due to the Abandon
check at 1190,
it's possible (though extremely unlikely) for an Abandon to arrive between the
start and end of a mod op, and cause the final decrement to be skipped still.
Probably need to do some restructuring to catch this, I'll look at this some more.
Never mind, syncprov_op_cleanup already catches these cases.
