Sigh.  I should test before I post.

The fix below is not sufficient.  It "mostly works" from inside the jail:

jailname : 14:44:06 /# service iws stop
jailname : 14:44:17 /# service iws start
jailname : 14:44:19 /# warn:    --minUptime not set. Defaulting to: 1000ms
warn:    --spinSleepTime not set. Your script will exit if it does not stay up for at least 1000ms
info:    Forever processing file: /usr/local/IWS4/app.js

But it doesn't work from outside the jail.  "service jail start" doesn't return to a shell prompt
unless I hit Ctrl-C.

hostname : 14:44:41 /root# service jail stop
Stopping jails: jailname
hostname : 14:44:45 /root# time service jail start
Starting jails:
load: 0.13  cmd: node 25865 [uwait] 94.17r 0.23u 0.03s 0% 33028k
^C

user    0m0.010s
sys     0m0.017s

hostname : 14:44:23 /root#
