Comment about the config, seeing as expiration is tighly linked to 
eviction, wouldn't it make more sense for expiration to be a subelement 
of eviction? i.e.

<eviction strategy="FIFO" wakeupInterval="1000" maxEntries="2000">
   <expiration lifespan="1000" maxIdle="500" />
</eviction>

I suppose expiration element attributes are not part of eviction element 
since they're primarily an optional feature and maxEntries is the main 
config option?
