OSError: AF_UNIX path too long

[Roman-Churakov]

Describe the bug
Since the release of behaveX 3.2.0 some of our builds have started to fail with 'AF_UNIX path too long' error.
(By saying 'some builds', I mean that we noticed that for the same repo a build for master is still OK, but a build for a branch has started to fail, even though is was OK yesterday.)
By pinning behaveX version to 3.0.0 we have achieved that our build is successful in all repos and branches.

Hi @Roman-Churakov, maybe the issue is related to a small change in the way we are using the multiprocessing library to start implementing a lock in a shared area.
We will analyze this. In the meantime, I have seen a workaround can be to export the environment variable $TMPDIR to a shorter path.
Regards,

@Roman-Churakov this was a worthwhile workaround for us:

TMPDIR=/tmp/ behavex -t=@tag --parallel-processes=10 --parallel-scheme=scenario

(instead of the usual behavex -t=@tag --parallel-processes=10 --parallel-scheme=scenario)
