If bots fail due to using this flag, the buildbot scripts have to be modified
to omit it. Regrtest ignores it anyway.

Moving subprocess execution of tests into a function.

Modern processors tend to make consecutive memory accesses cheaper than
random probes into memory.

Small sets can fit into L1 cache, so they get less benefit.  But they do
come out ahead because the consecutive probes don't probe the same key
more than once and because the randomization step occurs less frequently
(or not at all).

For the open addressing step, putting the perturb shift before the index
calculation gets the upper bits into play sooner.
