No.

I don't know if that's relevant, but at the same time when
the build takes place, one of the cores is rather loaded by
a shell script, which does lot's of disk r/w operations.
Could this be the cause? (BTW - can I safely "pause" a GRASS
shell script? I'd like to check if it's the culprit but
don't want to terminate it).
