Tried to run in patch queue:

027b7cf Remove redundant recursive umounts
c1bdc33 isar-events: Improve umount handler
b354273 ci: Wait for bitbake worker to finish before deleting artifacts
9cf29e6 isar-bootstrap: Fix and cleanup bind mounting
b354026 isar-image: umount base-apt when doing offline build
e965c0d gitlab-ci: Switch to ci_build.sh
...

After execution of problematic test case (I rebooted PC and executed 
steps in clean tree):

my stretch Debian system was entered into unusable state
as many important mounts were disappeared (see log of mount points
before and after execution  of last command attached).

Maxim.
