Differences From Artifact [4509cfc31c]:

• File tests/OFObjectTests.m — part of check-in [28170f5f65] at 2012-03-15 11:29:24 on branch trunk — Greatly improve OFObject's memory handling and performance.

  A linked-list is put before each memory chunk allocated instead of
  having an array of all memory chunks. This means only one malloc now
  instead of one malloc and one realloc. This also means that when
  checking reallocs and frees, it's no longer necessary to iterate through
  all memory chunks, as the linked list also contains the owner, meaning
  realloc and free are no longer O(n), but O(1) now.

  As allocating bigger chunks seems to be a little bit slower than smaller
  chunks, it seems that this is slightly slower in benchmarks if only very small
  chunks are allocated. However, measuring real world usage, it's a lot faster. (user: js, size: 2784) [annotate] [blame] [check-ins using] [more...]
