Reproducer could be something like this (untested)

# service luci start
# vim /etc/init.d/luci  # set LUCI_ZOPE_TIMEOUT=1
# <command to utilize the machine on 100% so luci stop is slow>&

Observed:

# service luci stop && pgrep -f luci
Shutting down luci:                                        [  OK  ]
31800

Expected:

# service luci stop && pgrep -f luci
Shutting down luci:                                        [ FAIL ]
31800
# grep '[lL]uci' /var/log/messages | tail -n1
[...] Luci did not stop after 1 seconds.

The issue is in bad handling of $? special variable in (1) the "if" inner
context and (2) the "while" outer context.  Bash man page says...

re (1):
> The exit status is the exit status of the last command executed, or zero if
> no condition tested true.

re (2):
> The exit status of the while and until commands is the exit status of the
> last do list command executed, or zero if none was executed.


Under this conditions, following snippet from stop function in luci
initscript:

> while [ $cur_wait -lt $max_wait ]; do
>         sleep 1
>         cur_wait=`expr $cur_wait + 1`
>         luci_running
>         if [ $? -eq 0 ]; then
>                 break
>         fi
> done

will always have, immediately after being executed, exit code of zero
and it makes no sense to use it in subsequent conditionals.

Action items:
a. fix stop function so that it works as per "Expected"
b. check the correctness of exit code handling in other parts of initscript
