Indexed Disk Cache , Remove expired Cache Item problem

[an...@axa.com.au]

If I put time to live for any cache item of  Indexed Disk Cache, cache 
item gets expired on time. 
It just gets removed from memory, as doRemove method is like this:.
.....
                return keyHash.remove( key ) != null;
...............

How that cache item and its value will get removed from actual file?

I'm calling doDispose as well, but it doesn't remove expired cache items 
from cache key/data file.

Here is debug info:
