+/* Create a memory pool with some flags specifying extended behaviour.
+ When flags is zero, the behaviour is identical to VALGRIND_CREATE_MEMPOOL.
+
+ The flag VALGRIND_MEMPOOL_METAPOOL specifies that the pieces of memory
+ associated with the pool using VALGRIND_MEMPOOL_ALLOC will be used
+ by the application as superblocks to dole out MALLOC_LIKE blocks using
+ VALGRIND_MALLOCLIKE_BLOCK. In other words, a meta pool is a "2 levels"
+ pool : first level is the blocks described by VALGRIND_MEMPOOL_ALLOC.
+ The second level blocks are described using VALGRIND_MALLOCLIKE_BLOCK.
+ Note that the association between the pool and the second level blocks
+ is implicit : second level blocks will be located inside first level
+ blocks. It is necessary to use the VALGRIND_MEMPOOL_METAPOOL flag
+ for such 2 levels pools, as otherwise valgrind will detect overlapping
+ memory blocks, and will abort execution (e.g. during leak search).
+
+ Such a meta pool can also be marked as an 'auto free' pool using the flag
+ VALGRIND_MEMPOOL_AUTO_FREE, which must be OR-ed together with the
+ VALGRIND_MEMPOOL_METAPOOL. For an 'auto free' pool, VALGRIND_MEMPOOL_FREE
+ will automatically free the second level blocks that are contained
+ inside the first level block freed with VALGRIND_MEMPOOL_FREE.
+ In other words, calling VALGRIND_MEMPOOL_FREE will cause implicit calls
+ to VALGRIND_FREELIKE_BLOCK for all the second level blocks included
+ in the first level block.
+ Note: it is an error to use the VALGRIND_MEMPOOL_AUTO_FREE flag
+ without the VALGRIND_MEMPOOL_METAPOOL flag.
