I don't think there's a real nice way to do this with heapq.  The
computer-sciencey way would involve separate balanced tree structures
for the two sorting keys (think of a database table with indexes on two
different columns).

You could look up "timing wheels" for a simpler practical approach that
the Linux kernel scheduler used to use (I think it changed a few years
ago).
