[oe] Multiple bitbake and a shared DL_DIR location - race conditions?

[Leon Woestenberg]

Hello,

in setting up a few automated builds, I have shared the DL_DIR amongst
the builds.

I would like to allow the builds to overlap in time, at least make
sure the builds are robust to this, but I doubt this is possible at
all.

Are there any race conditions with the current approach?

I.e. what if two fetch tasks from concurrent instances of bitbake
decide to download a package?

Regards,
