 * I am using Debian 8 x64 and the dotdeb repos with php 7 RC 6 builds and the first
   thing I wanted to do was test your redis plugin with the pecl extension I successfully
   built and installed just like I have for php5. I get a 500 internal server error
   when I activate the plugin and the error log shows this for nginx:
 *     ```
       Stack trace:

 * What’s the actual error exception that’s thrown? Should be found right above 
   the stack trace.

 * My apologies Till, this was a derpy moment. I built the redis-extension but forgot
   to install redis-server. Unsurprisingly I am now able to enable object cache 
   and all seems to be working.

 * That will teach me to test new environments at 1 am 😉
 * It would be nice if the plugin could detect this sort of grave oversight and 
   disable itself but I can understand if it’s not a priority.
