I've been working on qa/110 for awhile today and have a couple
of fixes, currently hacking on hopefully the last issue there.

Is the above commit related to 110?  With these other changes,
I think we'll be back to deterministic pmdasimple Installs - if
so, we wont need a pmcd restart.

I'll pull these & revert the above change if I reach nirvana in
pmdasimple today.  On qa/370 (sar2pcp), Lukas is also seeing some
new failures there on the buildbots ([*] maybe it _notrun before?)
- and I'm seeing some floating point flappiness from pmdumplog ...

$ diff 370.out 370.out.bad

<               245.0.NN (kernel.all.cpu.sys): value 0.0017

Lukas' looks more interesting though, may indicate a pre-existing
32/64 bit issue in some of the sar2pcp-created filesys metrics...
