Bug report

Bug description:

Initially reported in PR comments: #123413

There looks like three cases to investigate/work on from this:

  1. Gentoo + musl -> there is an extra mmap call
  2. Gentoo + sandbox -> many additional calls (Probably an environment to disable in if can detect)
  3. Should there be a more general switch to disable?

relates to: gh-120754

My first thought for 1 is mmap could generally be filtered out (it has shown up moderately frequently in my testing on other systems, generally used for memory allocation in wrapping). Working on setting up a Gentoo environment to test / experiment / investigate locally and develop patches.

pythongh-127076: Disable strace tests under LD_PRELOAD
460958b 
Distribution tooling (ex. sandbox on Gentoo and fakeroot on Debian) uses
LD_PRELOAD to intercept system calls and potentially modify them when
building. These tools can change the set of system calls, so disable
system call testing under these cases.
