[issue32045] Does json.dumps have a memory leak?

you are right. i realized later i actually had a leak in a com instantiated object, assumed it was a leak in the python and tried to find it using the gc module. 

The gc documentation led me down the garden path.

QUOTE

gc.garbage
A list of objects which the collector found to be unreachable but could not be freed (uncollectable objects). 

UNQUOTE

i assumed:
- cyclic references are unreachable but can be freed and hence collectable.
- __del__ finalizer (with cyclic references?) objects are unreachable and cannot be freed and hence uncollectable.
