All this can be discussed here. It is just an idea, I'm not sure about 
any details. Right now the level parameter is not needed to me, but may 
be other developers will need it.

May be the behavior should be opposite: clear caches of specified level 
and *lower*. Then by default only level 0 will be cleared and users will 
be able to use higher levels for long-living caches.
