ea24ac4b23 Correctly update the cache page-count when discarding pages in the xTruncate() method of the default pcache implementation. Otherwise the effective configured size of the cache shrinks each time xTruncate() is called. Fix for #3844. (CVS 6619)

6fa0fe13f0 Begin purging dirty pages from the cache once 90% of the cache is dirty (insteadof waiting until it is 100% dirty). This improves performance in some circumstances by effectively reserving 10% of the configured page-cache for frequently reused read-only pages. (CVS 6341)

062d4cb0ae If a page is made eligible for recycling when more than the configured maximum number of pages are allocated, free it immediately instead of adding it to the LRU list. (CVS 5638)
