There used to be a bug in the msys2 runtime which made certain processes
hang on exit in a non deterministic way.
So the parallel runs was disabled. I was looking into it but haven't been
able to reproduce it at all in months now since either upgrading msys2 or
Windows (to Windows 10).
We have a ticket with more information on it and what I found back then,
but haven't been able to progress.
It might be that they've just fixed it in the mean time.

Oh dear, why is that?
