You can also increase the timeout with the --timeout option.  However,
if it crashes no matter how long you let it run, that's a different
problem.

This is definitely not supposed to happen. Hopefully it's already been
fixed but otherwise a bug report is welcome!

I have a Core 2 Duo system with 3 GiB RAM and `guix pull` takes less
than an hour and doesn't swap.

I'd argue that it should not be, but due to the Guile bug it is. It may
not be enough to run `guix pull` — I don't know exactly how much memory
is required.
