It appears that the -w option doesn't enforce the requirement that
VARNISH_MIN_THREADS is >= 2. This causes issues with grace where
requests for cached content are blocked rather than served stale. Also,
the VARNISH_MIN_THREADS value in the default.vcl is set to 1 so this
should probably be updated to meet the 2 thread minimum requirement.
Feel free to contact me if there are any questions. This was already
discussed on IRC.<br>
