memcached_debug.c ?

[Randy Wigginton]

How would people feel about adding a "memcached_debug.c" file to the  
repository, that contains extensions that are not approved/ 
sanctioned?  For example, this would be the perfect place to put a  
"keys" command, in order to find out what keys are currently in the  
instance, or perhaps a "free_mem" command that evicted everything  
expired and returned the amount of free memory?

The idea is that these commands would only be available in the debug  
version of memcache; this would be the version to deploy to QA &  
staging environments, where performance is less important than the  
ability to look under the hood, so to speak.

Thoughts?
