[Maxim Cournoyer <maxim.cournoyer@gmail.com>]

Hello Guix,

I encountered the following (nondeterministic) test failure:

--8<---------------cut here---------------start------------->8---
# TOTAL: 13
# PASS:  12
# SKIP:  0
# XFAIL: 0
# FAIL:  1
# XPASS: 0
# ERROR: 0

error: in phase 'check': uncaught exception:
%exception #<&invoke-error program: "make" arguments: ("check" "-j" "24" "GUILE_AUTO_COMPILE=0") exit-status: 2 term-signal: #f stop-signal: #f> 
phase `check' failed after 15.3 seconds
command "make" "check" "-j" "24" "GUILE_AUTO_COMPILE=0" failed with status 2
--8<---------------cut here---------------end--------------->8---

Perhaps due to high load, as I can't seem to reproduce when building
Shepherd alone.

Thanks,
