Maximilian Michels commented on BEAM-9976:
------------------------------------------
Not sure it has to do with the temp folder. The reason you might not see
failures is that we are starting an embedded cluster which runs async from the
main test thread. There is a synchronization though via a latch.

I wonder if this is because there are multiple runs of
testSavepointRestorePortable, only one of which fails?
{quote}
There is only one run of that test and another run for
{{testSavepointRestoreLegacy}}.
