t/11-timeout.t fails on FreeBSD systems

[eserte]

The test suite fails on all my FreeBSD smokers (versions 9 .. 15):

#   Failed test 'No tests run for subtest "server replies quickly enough"'
#   at t/11-timeout.t line 37.
cannot open port: 127.0.0.1:27432 at /usr/perl5.38.2/lib/site_perl/5.38.2/Test/TCP.pm line 53.
# Tests were run but no plan was declared and done_testing() was not seen.
# Looks like your test exited with 255 just after 1.
t/11-timeout.t ........... 
Dubious, test returned 255 (wstat 65280, 0xff00)
Failed 1/1 subtests 

However, looking at http://matrix.cpantesters.org/?dist=Redis%202.000;os=freebsd;reports=1#sl=6,1 there are also systems (mainly BINGOS') with "green" reports.
