- * Testcase for defragmentation code.
- * We have testcases for:
- * - 2 fragments, aligned, [0,16),[16,32)
- * - n (50) fragments, [i*16,(i+1)*16)
- * - n (50) fragments, [0,i*16) + [50*16,51*16)
- * - n (100) fragments, inserted in interleaved order (holes in sequence)
- * - holes in sequence
- * - other overlaps
- * - timeouts
- * - multiple entries in GNUNET_hash-list
- * - id collisions in GNUNET_hash-list
