Actually, giving a warning and using the old default of 5 seconds should be good enough if perl doesn't work: >From 93015c3bebeca0cf2ed17ac0b561b7c3453864d8 Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyer...@redhat.com> Date: Thu, 4 Nov 2010 13:04:52 +0100 Subject: [PATCH] tests: don't hard-code a 5-second timeout; that's not always enough Instead, time the command in the C locale and use 10 times that duration -- rounded up to whole seconds -- as the timeout when running it in the UTF-8 locale. * tests/backref-multibyte-slow: Compute a performance-relative timeout.
