eldritch horrors cbf7929277 libstore: use thread pools for remote stderr handling
spawning threads is not free. reusing threads is also not free, but a
lot cheaper than spawning now ones. the difference can add up quite a
bit on nixos system evaluation; we've seen 20k threads cycled through
on even modestly sized configurations, and at 20µs per thread just to
launch and tear down (excluding any work done) that's potentially not
insignificant. in our test config this was a 3% eval time difference.
