Resubmitting with task end time put back in. This should allow us
to plot ${PN} tasks along an axis with various disk io to give
us a better idea where disk thrash is occurring
This commit adds disk-io statistics functionality on a build
and per-task basis. I've also started drying it up some.
We pull measurements for whatever partition TMPDIR exists on.
We pull /proc/diskstats for every task and the entire build and collect
I do no analysis in this, leaving that for the end user.
