+*-l* 'LIMIT'::
+
+ Allow at most 'LIMIT' requests to run concurrently. If a new
+ request is made when 'LIMIT' requests are executing, the new
+ request will wait up to ten seconds for one of them to
+ complete; if none does, the *ashd-wsgi* will assume that the
+ process is foobar and *abort*(3).
