20 The mt allocator [hereinafter referred to simply as "the allocator"]
21 is a fixed size (power of two) allocator that was initially
22 developed specifically to suit the needs of multi threaded
23 applications [hereinafter referred to as an MT application]. Over
24 time the allocator has evolved and been improved in many ways, in
25 particular it now also does a good job in single threaded
26 applications [hereinafter referred to as a ST application]. (Note:
27 In this document, when referring to single threaded applications
28 this also includes applications that are compiled with gcc without
29 thread support enabled. This is accomplished using ifdef's on
30 __GTHREADS). This allocator is tunable, very flexible, and capable
31 of high-performance.
32 </p><p>
33 The aim of this document is to describe - from an application point of
34 view - the "inner workings" of the allocator.
