-** If SQLITE_PAGECACHE_BLOCKALLOC is defined when the library is built,
-** each PGroup structure has a linked list of the the following starting
-** at PGroup.pBlockList. There is one entry for each distinct page-size 
-** currently used by members of the PGroup (i.e. 1024 bytes, 4096 bytes
-** etc.). Variable PGroupBlockList.nByte is set to the actual allocation
-** size requested by each pcache, which is the database page-size plus
-** the various header structures used by the pcache, pager and btree layers.
-** Usually around (pgsz+200) bytes.
-**
-** This size (pgsz+200) bytes is not allocated efficiently by some
-** implementations of malloc. In particular, some implementations are only
-** able to allocate blocks of memory chunks of 2^N bytes, where N is some
-** integer value. Since the page-size is a power of 2, this means we
-** end up wasting (pgsz-200) bytes in each allocation.
-**
-** If SQLITE_PAGECACHE_BLOCKALLOC is defined, the (pgsz+200) byte blocks
-** are not allocated directly. Instead, blocks of roughly M*(pgsz+200) bytes 
-** are requested from malloc allocator. After a block is returned,
-** sqlite3MallocSize() is used to determine how many (pgsz+200) byte
-** allocations can fit in the space returned by malloc(). This value may
-** be more than M.
-**
-** The blocks are stored in a doubly-linked list. Variable PGroupBlock.nEntry
-** contains the number of allocations that will fit in the aData[] space.
-** nEntry is limited to the number of bits in bitmask mUsed. If a slot
-** within aData is in use, the corresponding bit in mUsed is set. Thus
-** when (mUsed+1==(1 << nEntry)) the block is completely full.
-**
-** Each time a slot within a block is freed, the block is moved to the start
-** of the linked-list. And if a block becomes completely full, then it is
-** moved to the end of the list. As a result, when searching for a free
-** slot, only the first block in the list need be examined. If it is full,
-** then it is guaranteed that all blocks are full.
