Hi folks,

I came across this a week or so ago and it came back to mind because of
the openblas kerfuffle [0].

arpack-3.9.0 will in some cases give deterministic failure as the
randomness in the retry mechanism seems busted.

This can cause e.g. igraph's test suite to fail.

Ths discussion is quite long and the second bug linked tries
to summarise it. It's complicated and for now I've just yanked
arpack-3.9.0 in Gentoo (masked it).
