Difference between `pytestqt.exceptions.TimeoutError` and Python's `TimeoutError`

Python has a TimeoutError already: https://docs.python.org/3/library/exceptions.html#TimeoutError

What is the purpose of pytestqt.exceptions.TimeoutError, which is not derived from TimeoutError? It is very easy write a

try:
  ...
except  TimeoutError:
  pass

that does not work as intended because one is missing from pytestqt.exceptions import TimeoutError (which by the way gives:

Redefining built-in ‘TimeoutError’

in pylint).

I think pytestqt.exceptions.TimeoutError could be removed or, if it should be kept for compatibility, it should derive from TimeoutError.

I agree with @The-Compiler.

However we could rename it to something else to avoid confusion, say QtTimeoutError, or something like that.

Python’s TimeoutError is a subclass of OSError, and its description is:

Raised when a system function timed out at the system level. Corresponds to errno ETIMEDOUT.

What’s timing out in pytest-qt is not related to system functions, OS calls or errno in any way. pytest-qt raising an OSError for something not related to the OS at all seems like unnecessarily confusing to me, so I’m -1 on this.
