I'm ok with private function. But you need to make it available to
tst_common.h. We could use extern. But not sure if this is what we
want.

On the other hand, we could make it as lib function, so others, who
need to set timeout in arbitrary way, have a utility to adjust there
timeout in a generic way. WDYT? But we also could leave this for later,
and simply change it if really needed.

Thanks
