Description

Create 3 jobs - master and slave tests and supportserver for them
define a PARALLEL_WITH as suggested in https://github.com/os-autoinst/openQA/blob/master/docs/WritingTests.asciidoc master and slave has PARALLEL_WITH=supportserver , supportserver don't have PARALLEL_WITH

==> during execution jobs slave would stuck on waiting for mutex from master , which master already successfully pass

Example :
https://openqa.suse.de/tests/1627328
https://openqa.suse.de/tests/1627329
https://openqa.suse.de/tests/1627327

Note: I will revert PARALLEL_WITH setup to one which stated by tools team as "wrong" (see https://progress.opensuse.org/issues/32545) since this one generally works just fails sporadically from time to time. So you can't reproduce issue by just re-trigger jobs on osd

@asmorodskyi:
Documentation talks about mutexes on parents/children. Siblings are not mentioned anywhere ;)
Jobs can lock mutexes owned by siblings if you provide mutex owner (jobid) when calling mutex_lock.

Sibling unlocking is not implemented yet, should be fixed by those:
