[NoDriver] performance decreases after sequentially created browser instances.

[gnori-zon]

That is, the first 5 instances will work faster than the next ones. This ultimately leads to dependencies and very slow performance.

If you stop and restart the docker container that is running, performance will improve, but after a while it will drop again. I think this is because there are zombie processes left (crome_crashpad, crome, cat) that are children from Python (application)

Scenario:

• open 5...some work...close 5,
• open 5...some work...close 5

Pls, tell me your guesses)

I don't know if it's an issue, but since the deconstruct_browser() function from core/util.py is being called only when the program exits, the __registered__instances__ set increases after every uc.start() and it doesn't decrease until the program exits. Also, the browsers' data dirs are being removed only when the program exits.
