qa/787 will fail for everyone else for the time being ... I have libpcp changes 
that reduce the number of log I/Os to 1/3 or 1/4 of their previous values in 
the bad cases.  The qa test shows these numbers.  But unfortunately the libpcp 
code is not yet ready for checkin.

This commit is to (a) reserve qa/787, and (b) show Frank that I have not 
forgotten about this problem ... 8^)>

Expect the real libpcp fix in late June when I'll be back.

    qa/787 (new) - exercise slow archive reading
    
    Uses the reduced version of Frank's archive that used to show
    really excessive log I/O for some metrics in the presence of
    <mark> records.

    qa/slow archive
    
    This is a reduced version of Frank's archive
    (super-SLOW-merged-archive-20140124.225919) that demonstrates
    really excessive log I/O for some metrics in the presence of
    <mark> records.
