Hi,

I think there is an issue with memory allocating with threading.Timer in 3.8.0/3.8.1.

When I run the attached code in Python 3.7.3 I get a memory consumption of approx. 10 MB. If I run the same code with python 3.8.0 or 3.8.1, it keeps consuming memory (several hundreds of MB). 

I've attached 3 images where I run the attached script under mprof.

By inspect of the output from tracemalloc, I can see that 
/usr/lib/python3.8/threading.py:908 keeps allocating memory.

I have tested this with python 3.8.0 from ubuntu 16.04 repository and python 3.8.1 from source. Both versions suffers from the memory consumption issue.
