Unhandled `PermissionError` for `/proc/stat` via `psutil`

[luckyabsoluter]

I'm encountering a PermissionError when running SeleniumBase v4.49.3 in a Termux android

The issue originates from psutil attempting to read /proc/stat, which is restricted by SELinux policies in this specific environment. SeleniumBase currently crashes because it doesn't catch the PermissionError (giampaolo/psutil#2195). The psutil maintainer clarified there that apps must handle this exception.

Suggested Solution:
Since we cannot guarantee access to /proc/stat across all environments (especially mobile terminals like Termux), calls to psutil that read restricted system files should be wrapped in a try-except block. Catching PermissionError and gracefully falling back or ignoring the stat retrieval would prevent the entire script from crashing.

Caused by:

• Orphaned Chromium process causes persistent user_data_dir lock after crash #4349

Note: Since native tools like top work fine in Termux, it isn't entirely impossible on Android. There is still room for improvement within psutil itself.

In 4.49.4 (https://github.com/seleniumbase/SeleniumBase/releases/tag/v4.49.4), which was just released, all psutil calls coming from SeleniumBase methods now handle the PermissionError: 74ee362.

is_running() now returns None if PermissionError is encountered.

But any direct calls to psutil from your scripts could still lead to PermissionError since that is a separate repo.
