cabal hardcodes the maximum number of build jobs to 64:
cabal/Cabal/Distribution/Simple/Setup.hs
Line 2240 in b402dc8
When reviewing #1142, I didn't see a specific rationale given; maybe this was just trying to restrict it to a sane set of values, or avoid typos? We ran into this in Homebrew - Homebrew/legacy-homebrew#49509. Homebrew sets the number of build jobs to the number of threads, usually 2x the number of CPUs. The user in question has a server with two 18-core CPUs, or 72 logical threads, so Homebrew automatically sets 72 build jobs for most software; since this is above the magic number of 64, cabal-install errors out.
