[Nix-dev] Hydra queue is in a weird state

[Vladimír Čunát]

Hi,
around 24h ago I merged some older staging commit, and Hydra somehow
hasn't recovered since.

Most of jobs should've been cached from staging - mainly except for
Haskell stuff because that got updated on master in the meantime - but
apparently those jobs are stuck in the queue, not being processed in any
way.  The machines were reportedly idling a lot yesterday after that
(now they picked some subsequent jobs on staging).
