I noticed that this gem failed to restart unicorn after I upgraded to v0.2.0, due to the missing of app_path.

0.2.0

executing "if [ -e tmp/pids/unicorn.pid ] &&  kill -0 `cat tmp/pids/unicorn.pid` >

0.1.10

executing "if [ -e /u/apps/avcloud/current/tmp/pids/unicorn.pid ] &&  kill -0 `cat /u/apps/avcloud/current/tmp/pids/unicor

I'm using a multistage cap. Not sure if that's related.

It happens on unicorn:stop, restart etc.
