Hi, I've been using Solr for some time and i would like to contribute a little. 
I found on Jira an improvement that seems to be easy to implement (I don't want 
to go with the most difficult ones until I get completly familiar with Solr 
code), the one on the Subject of this mail: SOLR-571:LRUCache autowarmCount 
should support percentages.

I was thinking in modify both, the FastLRUCache and the LRUCache to allow 
percentages (as well as absolute values of course) on "autowarmCount" 
parameter, and in the case of a percentage, simply evaluate it on the "init" 
method.

For example, when "size" parameter is 1000 and "autowarmCount" parameter is 
"50%", simply set the field autowarmCount in 500. 
Does someone see a potential problem here? 

Tomás
