So the skip was on purpose and to avoid signal propagation issues seen
on some older systems:
http://git.sv.gnu.org/gitweb/?p=coreutils.git;a=commit;h=v8.14-30-g6603e37

This initial failure is worrying, though may be a false positive
due to your shell or something. What versions of dash, bash, kernel
do you have there? I can't reproduce at all here with any
shell, though you might have older versions.

What is your system /bin/sh, dash or bash?
Note you can force a particular SHELL as follows,
and it would be interesting to see if the issue affected all shells.

make check TESTS='tests/misc/timeout-group.sh' SUBDIRS=. VERBOSE=yes SHELL=bash

Hopefully we can come up with a skip for this case too.

thanks,
Pádraig.
