Segfaults caused by 'import plateau' in CI

[IzerOnadimQC]

Occasionally, the CI pipeline fails with a seg fault during the 'Test import' stage. Specifically, most of the time the segfault occurs during import plateau.api.serialization or import plateau.serialization with pyarrow 10.0.1, however, it has also happened when importing other modules within plateau, and with other pyarrow versions. It doesn't happen all the time, and it always goes away upon the second or third time re-running the CI job.

For example, in this job the first attempted produced a seg fault, but the second passed.

/home/runner/work/_temp/30f92123-be37-4fc8-bb7e-ecd68eb49daa.sh: line 8:  3592 Segmentation fault      (core dumped) python -c "import plateau.serialization"
Error: Process completed with exit code 139.

Ideally, we should find the source of these seg faults, probably by comparing successful and failed runs, and eliminate them to avoid the hassle of re-running the pipeline.

This was a transitory issue which seems to have resolved itself, so I'll close this issue for now and re-open it if the problem crops up again.
