asv bechmarks trigger "No module named 'profiling.tracing'" error on 3.15.0a8

Bug report

Bug description:

You can reproduce this by installing 3.15.0a8, creating a venv that includes the asv package, and doing asv run in the root of this test repository:

https://github.com/ngoldbaum/asv-test

I triggered this originally in NumPy using the spin bench command there but it seems to happen for any asv invocation. It doesn't happen in Python 3.14.

I get this error related to the new profiling package:

I expect this is a conflict between the new https://github.com/python/cpython/tree/main/Lib/profiling package and https://github.com/airspeed-velocity/asv/blob/main/asv/profiling.py.

See https://docs.python.org/3.15/whatsnew/3.15.html#whatsnew315-profiling-package

Can asv rename profiling.py?

Thanks for explaining what’s happening. Closing in favor of airspeed-velocity/asv#1584.
