Hi,

I've noticed that tests/publish.scm fails when run with the other tests
in parallel (see attached test-suite.log file).  Specifically, it fails
when I run "make -j check".  It passes when I run "make check".  It
passes when I run "make -j check TESTS=tests/publish.scm".  It also
passes when I run "make check TESTS=tests/publish.scm".  Here's the
failure message:

I'm using GuixSD with Guix v0.10.0.  I observed this failure using
commit 8d63dddac11882ef85283bda259e0142b65ae28f.  I built guix with
dependencies provided via "guix environment guix"; however, since there
are two versions of guix defined gnu/packages/package-management.scm,
I'm not sure which one is being used to determine dependencies.
