import_from_depot size limitation

Hello Genodians

Is there a limit to the size (number of bytes or number of files) that
can be added via import_from_depot (ARCH: imx6, KERNEL: hw)?

I had a problem with a run script that sometimes hung (mkfs never
completing) or sometimes crashed in different components (ip pointing to
Genode::ipc_reply_wait() in after upgrading  from 19.05 to 19.07.

To debug the error I created a small version and step by step increased
its size until it was identical to the one with the error.

The last difference I found was that the script with the error imported
more depot archives.
After reducing the list of imported archives the run script now works well.

What I think is even stranger, at first I bisected the problem with the
original run script. This resulted in commit ac0ecdf855f61 triggering
the problem. But as non of my other run scripts showed this kind of
error, I suspected that it only uncovered a hidden error in my run script.

Could it be, that this is related to the size of the resulting image
(about 50MiB for image.elf and 26MiB for uImage)?
