----------------------+-----------------------------------------------------
 On a site with a relatively busy purge list, the following command fails
 most of the time:

 {{{
 # varnishadm -S /etc/varnish/secret -T localhost:6082 purge.list
 CLI communication error (body)
 Command failed with error code 400
 }}}

 "Relatively busy" being defined as:

 {{{
 # varnishstat -1 -f
 n_purge,n_purge_add,n_purge_retire,n_purge,n_purge_obj_test,n_purge_re_test,n_purge_dups
 n_purge                 11434          .   N total active purges
 n_purge_add             13699         0.04 N new purges added
 n_purge_retire           2265         0.01 N old purges deleted
