FWIW, I'm a bit suspicious of relocating the temp stats directory as
being a reliable fix for this. It looks to me like hamster isn't that
much slower than gaur/pademelon, ie the same machine that was my primary
development machine for well over a decade, and on which I have NEVER
seen a "stats collector not responding" failure. Plus, if hamster's
main storage is SSD, that seems unlikely to be slower than the spinning
rust in gaur/pademelon. So I can't escape the suspicion that something
else is going on there. Seemingly-unexplainable stats collector problems
have been a bugaboo for a long time ...
