If you perform an action under a "warn" ACL verb then a temporary
failure of the expansion will not cause the ACL to defer, instead
you get a log line and the ACL will continue at the next verb.
Perhaps you can under a warn "verb" set some ACL variable and then use
an "accept" or "deny" verb to act on the content of the variable. in
the case of a timeout the line with $run will be ignored, so the
variable will be unaltered.
