i don't think it's resaonable because it is pointing out a real
issue.  what could happen is that two "dependall" phases could
enter at the same time and stomp on each other, and the "-p" fix
will paper over one symptom of the real problem (the one that
actually catches stuff, it seems, since this is a long standing
problem that appears to exist in multiple places.)

we should fix the SUBDIRs lists.
