957026ac78 Defer the bulk pcache1 memory allocation until the first page allocation
request.  Limit the size of the pcache1 bulk allocation to the cache_size
setting.  Deallocate the bulk allocation on a sqlite3_db_release_memory()
request, if the bulk allocation is completely unused.

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)

ee03d629f5 Conjecture: a journal header with nRec==0 must be the last header in the

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)
