- * - no configurable allocation policy (how big blocks should be allocated)

- * - no thread synchronization at all

- * 2. Allocated block contains the blob header (see CHdr) followed by the raw byte data.

- * 4. The pointer (in ptr_u) points behind the header (to the first data byte).
- * When memory block is allocated, the sizeof(CHdr) it added to it.
- * 5. Benefits of this layout:
- * - items are accessed in the simplest possible way - just dereferencing the pointer,

- * - sizeof(blob) is the same as the size of any other pointer
- * 6. Drawbacks of this layout:
- * - the fact, that pointer to the alocated block is adjusted by sizeof(CHdr) before
