I was spot checking the grenade multinode job to make sure it looks like
it was doing the correct thing. In doing so I found that ~15minutes of
it's hour long build time is compiling lxml and numpy 3 times each.

Due to our exact calculations by upper-constraints.txt we ensure exactly
the right version of each of those in old & new & subnode (old).

Is there a nodepool cache strategy where we could pre build these? A 25%
performance win comes out the other side if there is a strategy here.
