The test 't5800-remote-helpers.sh' hangs on my Linux desktop (where I have
installed a custom simple-minded firewall based on iptables).  This does
not happen on remote systems I use for testing, so I guess the problem
lies with my machine.  Still, having the test to hang is unnecessarily
harsh and user-unfriendly IMHO, and it would be better to detect the
situation and SKIP or FAIL the affected test cases instead.

For reference, here is the output of the test 't5800-remote-helpers.sh' run
with the '-v' option:

At this point, the test hangs, and I have to manually kill it with a SIGINT,
the result being:

If I run ps(1) in another terminal before interrupting the hung test, the
following command sticks out as a possible culprit:

git-fast-import --quiet --export-marks=/devel/stefano/src/git/t/trash \
directory.t5800-remote-helpers/localclone/.git/info/fast-import/\
