Few people know that this property has absolutely no effect.  :-)

It used to be that Hydra would honor it.  But Cuirass has never honored it.

It’s not clear to me whether Cuirass should honor it, in fact.

At the Guix level, timeouts are per session: you set them for all your
session with ‘set-build-options’.  So if you want them per-derivation,
you basically need to create one session per derivation build; that’s
what Hydra did.

But there’s a good reason for it to be per-session: the admin may want
to be in control of those parameters.  For example, on berlin, we’d
rather make sure machines don’t stay idle for too long.

Thoughts?
