Contains both a stand-alone and a replacement memory manager. The significant enhancements are:

1) Returns highly aligned memory blocks.

2) Non-thread blocking (replacment version)

3) Fast

The stand-alone manager is HPMM and the replacement manager is MultiMM and is based on HPMM.

Using HPMM requires creating an instance of TMemManager and then calling GetMem, FreeMem and ReAllocMem as needed.

Using MultiMM is simply a matter of placing it as the first entry in the uses clause of the program (.dpr) file. All subsequent memory requests will be routed through MultiMM. Note: MultiMM patches the system unit to catch thread terminations and clean up appropriately.

For more information on the memory manager see

Version 1.1 fixes a memory leak from threadmanagers being reused. And by default blocks are no longer split on reallocMem requests.

Version 1.2 fixes a potential memory leak from externally created threads (typically API callbacks)
