I'm OK with this change, but this doesn't solve problems
with hangs - when commands are launched by hand:

Command 1)
bitbake  -c cache_base_repo multiconfig:qemuarm-stretch:isar-image-base 
multiconfig:qemuarm64-stretch:isar-image-base multiconfig:qemuamd64-
stretch:isar-image-base

At this step I've doublechecked  that bitbake.sock is cleaned.
Command 2)
sudo rm -rf tmp

Command 3)
sed -i -e 's/#ISAR_USE_CACHED_BASE_REPO ?= "1"/ISAR_USE_CACHED_BASE_REPO 
?= "1"/g' conf/local.conf

No problems detected at this point - the same mounts etc.

The next command hangs on the last task (according strace bitbake tries 
to unmount /sys /dev)

Command 4)
bitbake multiconfig:qemuarm-stretch:isar-image-base 
multiconfig:qemuarm64-stretch:isar-image-base 
multiconfig:qemuamd64-stretch:isar-image-base

Maxim.
