Another pdbox patch by Wincent Balin (FS #10416): switch to using TLSF as memory allocator. Probably the last patch I commit for him, next changes are for him :)

1Package: dbestfit - a dynamic memory allocator
2Date: March 30, 2005
3Version: 3.3
4Author: Daniel Stenberg <daniel@haxx.se>
5
6 I wrote the dmalloc part for small allocation sizes to improve the behavior
7of the built-in (first-fit) allocator found in pSOS (around 1996).
8
9 I wrote the bmalloc part (best-fit with splay-tree sorting) just for the fun
10of it and to see how good malloc() clone I could make. The quality of my
11implementation is still left to be judged in real-world tests.
12
13TODO:
14 * Remove the final not-so-very-nice loop in dmalloc.c that checks for a block
15 with free fragments (when the list gets longer too much time might be spent
16 in that loop).
17
18 * Add semaphore protection in bmalloc.
19
20 * Make a separate application that samples the memory usage of a program
21 and is capable of replaying it (in order to test properly).
