Since a couple days, Craps exhibits a new problem, where the
evaluations on master appear stalled, showing as "In progress..."
Eventually, it seems the maximum number of PostgreSQL connections
allowed (300, if what Ricardo wrote on #guix is accurate :-)) is
reached, and we get the following error:

Restarting postgresql workarounds the above error, but it doesn't fix
the hang, and the problem connection problem recurs.
I've logged at the Cuirass and messages logs, but I haven't spot
