Cache.getIfPresent with valueLoader

[GoogleCodeExporter]

Hi there,

I'd propose an additional <T> T getIfPresent(Object key, Callable<T> 
valueloader) method that behaves just like getIfPresent(Object key) and 
immidiately returns the value (or null) but will load the value in the 
background.

As Cache.get(Object, Callable<T>) blocks until the value has been loaded the 
proposed Cache.getIfPresent(Object, Callable<T>) method would not be blocking. 
This comes handy if the valueloader does some heavy lifting and should only run 
once per key.

Thanks in advance,
Arman
