This is terrible, but you can work around it by passing a large value to
the --max-silent-time "common build option":
     
--max-silent-time=seconds

    When the build or substitution process remains silent for more than seconds, terminate it and report a build failure.

Out of curiosity, what kind of machine are you using? A full hour with
no output at all indicates that something is happening very slowly! Is
it swapping?

Do you mean that the computer becomes unresponsive?

I don't know exactly, but during `guix pull` Guix is built from source
with the Guile compiler.

There are some bugs in the current version of the Guile compiler that
cause it to require way more memory than expected. This is terrible on
memory-constrained systems because it forces the use of swap, which is
typically super slow. Hopefully we can deploy a fix soon.
