More info: Things work fine with jail_parallel_start="YES".
In 10.4, /etc/rc.d/jail now adds "-p1" to the jail command's arguments
when starting all jails with jail_parallel_start="NO". It's definitely
this parameter that's causing my problems -- changing /etc/rc.d/jail to
not add the parameter fixes the problem.
