re: run 3 did not freeze -- a counter-example to my own inducer hypothesis

Browse Source 
Third run with the inducer on from flight start went 900s without freezing, so
the tally is 2 for / 1 against. Stated confound: the inducer was far weaker this
run (~47-50s per CPU pass vs ~4.2s in run 2, because two subagents were
saturating the box -- 22 passes in 15 min instead of ~150). That is consistent
with either reading, so it is not scored as a confirmation. What it does
establish is that the inducer is not sufficient, and that future runs must
report its measured rate rather than just that it was on.

Second healthy stability sample: 9 stable / 14 vary vs 12 / 13 in the first,
intersecting to only 8 threads. So the stable set is run-dependent and must be
measured within the run it is used in -- the same lesson as gdb thread numbering,
one level up.

The frozen half of the distribution experiment is still uncollected.

Only a thread in the STABLE set can carry a frozen-state signature;
a VARIES thread differing when frozen proves nothing.
