I’m currently updating many Haskell packages and I applied this patch to
make this job easier.  It works as advertised.

I think it could be less verbose (because something like this won’t
happen in a released version of Guix and is only useful to developers).
I’m no longer convinced that it should be a separate tool; it is an
improvement over having “guix build” hang indefinitely.  I’d much rather
have “guix build” fail on its own than requiring me to lose patience and
hit Ctrl-C.
