2013-03-11page_cache: dup memory on insertPeter Lieven1-1/+1
The page cache frees all data on finish, on resize and if there is collision on insert. So it should be the caches responsibility to dup the data that is stored in the cache.

2013-03-11page_cache: fix memory leakPeter Lieven1-0/+3
XBZRLE encoded migration introduced a MRU page cache meachnism. Unfortunately, cached items where never freed in case of a collision in the page cache on cache_insert(). This lead to out of memory conditions during XBZRLE migration if the page cache was small and there where a lot of collisions in the cache.
