Sporadic timeouts in oci_container.py

[tvalentyn]

Description

We observe in apache/beam#28703 that cibuildwheel in our github action runs sometimes fails with a time out after the wheel is built. The 30 second timeout seems to be hardcoded in

cibuildwheel/cibuildwheel/oci_container.py

Line 185 in 886ba0f

self.process.wait(timeout=30)

. we plan to work around by adding retries on our end, but wondering if cibuildwheel should increase the timeout or add some retry logic that would benefit all users.

Any idea what the container is doing that's making it take so long to close? The self.process.wait(timeout=30) is simply waiting for a bash shell in the container to exit (having received an exit command), so it seems to me likely that something has hung somewhere, normally this takes a fraction of a second.
