However, unless you're storing a strong reference to the poset, you

Well... About always when I want to compute something longer than for
4..24 hours, I will be out of memory.
This is an artificial example to show what I mean. Let this run for
several minutes:
P7 = Posets(7).list()
i = 0
while True:
for P in P7:
if i%1000 == 0:
print i, get_memory_usage()
M = P.width()
i += 1
Compare with P.height() that does not eat memory.
