Hello! I think I've stumbled across an issue similar to this one:
https://github.com/protocolbuffers/protobuf/issues/10088

But I'm not entirely sure, so seeking help.
I've forked and hacked together a little demo 
repo: https://github.com/viktorvorobev/proto_leak

But basically the situation is as follows.
If you create a proto object, then use `ParseFromString` on it multiple 
times, then the object size grows uncontrollably until this object is 
deleted:

obj = schema_pb2.value_test_topic()
for _ in range(10_000_000):
     # here the object will grow
    obj.ParseFromString(b"...")
del obj

But if you recreate an object every time, then everything seems to be fine, 
so this code doesn't leak:

for _ in range(10_000_000):
    obj = schema_pb2.value_test_topic()
    obj.ParseFromString(b"...")

I suspect the same behaviour for Unpack, but didn't test it myself.

Is this known or intended?

Thanks a lot!
