Something that struck me is that the animals that stayed green were
almost exclusively Debian and macOS, while the unhappy ones were
uniformly not.  That pattern makes no sense --- why would Debian
act differently from other Linuxen? --- but it sure seems real.

[ looks a bit more... ]  Actually, most of those Debian machines
are Andres' test menagerie.  So maybe there's some commonality
of configuration of his animals that is connected to this.

Anyway, it looks like I can probably reproduce it on florican's
host, if you still need help understanding it tomorrow.  But
I remain really dubious that this can work at all.  Question:
have you tried that test under CLOBBER_CACHE_ALWAYS?
