qa/455 badness ... test is hanging all over the QA Farm

[Ken McDonell <kenj@xxxxxxxxxxxxxxxx>]

The test has regressed badly in the last day or so ... it is hanging (I 
think) in this line
$sudo sh -c "cat $tmp.stats >> $PCP_LOG_DIR/rsyslog/stats"

and it looks like $PCP_LOG_DIR/rsyslog/stats exists but cannot be 
written to, which suggests the PMDA may have exited ... but rsyslog is 
not configured in pmcd.conf and does not appear in pmcd.log ... so it 
looks like the Install from qa/455 never got very far.
pmdaproc changes may be?

I don't have time to diagnose this now and I'll be away from home for 
several days so I have to shut down the QA Farm (it will explode if all 
40 VMs are running at once).
