[New-bugs-announce] [issue33444] Memory leak/high usage on copy in different thread

[MultiSosnooley]

New submission from MultiSosnooley <multisosnooley at gmail.com>:

On linux (ubuntu 16.04, 18.04 tested) with python 3.6.5, 3.5.5 and 3.7-dev (windows is not affected) there is ~850Mb of memory used by python process at sleep point. Replacing `submit` `result` with plain function call causes normal ~75Mb at sleep point.
Maybe it is linux side issue (or normal behavior).
