[phk at projects.linpro.no]

Author: phk
Date: 2008-11-10 10:40:39 +0100 (Mon, 10 Nov 2008)
New Revision: 3368

Added:
   trunk/varnish-cache/bin/varnishtest/tests/v00022.vtc
Log:
Add a test of the random director that uses actual randomness.

This will be skipped on platforms where srandom(1) does not result
in the same deterministic sequence of random numbers as on FreeBSD
and Linux.
