Big Buffer Test Under Windows NT

These are test results of our allocator comparison.

Legend

Parameter	Description
`etype = MS_CRTL, ptype = ?`	Microsoft Visual C++ 6.0 SP3 `malloc`/`free`
`etype = MS_COM, ptype = ?`	Operating System allocation via COM's `IMalloc` interface
`etype = MS_HEAP, ptype = ?`	Operating System allocation via `HeapAlloc/HeapFree`
`etype = DL, ptype = ?`	Doug Lea's `malloc`/`free`version 2.6.6
`etype = OWN, ptype = MS_HEAP`	Our allocator, page allocation via `HeapAlloc/HeapFree`
`etype = OWN, ptype = MS_VIRTUAL`	Our allocator, page allocation via `VirtualAlloc/VirtualFree`
`etype = OWN, ptype = OWN`	Our allocator, page allocation via our system allocator
