Python3 version (python3 -V -V): Python 3.8.10
Steps to reproduce
Borrowing code from #55:

print()
c = 0
while True:
fz = frozendict.frozendict({i: i for i in range(1000)})
_repr = repr(fz)
if (c % 10000) == 0:
max_rss = resource.getrusage(resource.RUSAGE_SELF).ru_maxrss
print(f"iteration: {c}, max rss: {max_rss} kb")
c += 1Actual result
frozendict version: 2.3.2
iteration: 0, max rss: 11712 kb
iteration: 10000, max rss: 118104 kb
iteration: 20000, max rss: 224496 kb
