Too many Python scripts

I'm using an iPhone 8 running iOS 16.0.3 and latest a-shell version (build 270) from TestFlight.

If I try to run e.g. `pip install bpytop` or `pip install -r requirements.txt` (from a project with multiple dependencies), I get the following error in an alert window: `Too many Python scripts. Too many Python interpreters running at the same time. Try to close some of theme.` (I can't attach a screenshot because this iPhone isn't mine).

## How to reproduce this bug

Same as above or try to run the following commands:
`$ python`

`>>> import os`

`>>> os.system("python")`

Run again last two commands in the new interpreter and you'll get an error like this:
`Failed loading notAValidCommand from python3_
ios.framework/python3_ios, cause = dlsym(0xa5
3c8720, notAValidCommand): symbol not found`
