Ok, thanks for the explanation. You unshared the host rootfses for Debian armhf
and Raspbian armhf. After that, the locks in isar_bootstrap() and
do_apt_config_prepare() are indeed not necessary.
Actually, sharing both was an intended optimization because the resulting host
rootfses are identical. However, the implementation drops one via locking and
not via bitbake pipeline, and isn't executed on config change. Not sure how
difficult it would be to do that right. I can merge #9 and #10 for now.

I've forgotten that hello is unpacked for every arch-codename, so each has its
own once.do_dpkg_build. Never mind.
With kind regards,
Baurzhan.
