+/** A memory pool allocator.

+    If a request arrives for allocating \c n bytes then it is first
+    rounded up to the nearest multiple of \c sizeof(void*) (this is \c
+    n_roundup), then one more \c sizeof(void*) is added to this
+    number. If the result is no more than maxpooled_ then
+    the appropriate pool is used to get a chunk of memory, if not,
+    then malloc is used. In either case, the size of the allocated
+    chunk is written into the first \c sizeof(void*) bytes and a
+    pointer pointing afterwards is returned.
