Bug#1091613: python3-adios4dolfinx: test failure: test_original_checkpoint.py usually times out

[Drew Parsons]

Package: python3-adios4dolfinx
Version: 0.9.0-2
Severity: normal
Control: forwarded -1 https://github.com/jorgensd/adios4dolfinx/issues/147

There is some flakiness in test_original_checkpoint.py
(test_read_write_P_*). It regularly times out.

Perhaps there's some race condition, occasionally it passes. The time
out occurs randomly at different specific tests,
e.g. test_read_write_P_2D[create_2D_mesh3-True-4-Lagrange-True], or
test_read_write_P_2D[create_2D_mesh1-False-4-Lagrange-True], or
test_read_write_P_3D[create_3D_mesh3-False-1-Lagrange-False]

Test failures can be seen in debian CI testing at https://ci.debian.net/packages/a/adios4dolfinx/
For instance https://ci.debian.net/packages/a/adios4dolfinx/unstable/amd64/
shows 30 of the last 42 tests failing (not necessarily all due to the
time-out problem).

I can reproduce the problem locally on my own system. Tests passed
once when building the debian package for adios4dolfinx 0.9.1.post0,
but then hit the timeout when running CI tests (autopkgtest on
debian/tests) using the built package.
