Bug#976404: mpi4py: flaky ppc64el autopkgtest on ci.debian.net: regularly times out

Dear maintainer(s),

The autopkgtest of your package turned up a couple of times on our list
of regressions. I looked into the history of your autopkgtest and it
fails regularly on ppc64el [1] due to time out.

Because the unstable-to-testing migration software now blocks on
regressions in testing, flaky tests, i.e. tests that flip between
passing and failing without changes to the list of installed packages,
are causing people unrelated to your package to spend time on these
tests.

I copied the output at the bottom of this report.

Please do get in touch if we need to dive into this together.

Paul
