(cleaned screenlog just gets rid of control characters and me viewing the makefile, but i attached both to be safe)

CPython versions tested on:

Operating systems tested on:

RPi OS is a tier 3 platform (see PEP-11) so it's supported, hence I'm categorizing it under OS-linux.

However, I don't know if your platform falls under this one so I'm asking @gpshead

[gpshead]

Our buildbot is a RPi 5 and used to be run on a 4. The 3 and lower are quite slow - we're not going to test or maintain our timeouts for such a platform.
