After contributing to the development of later FastSharemem versions, reader Ai Ming (from China, I think) has submitted his own version of a Sharemem replacement. It uses a different mechanism, and you can download it from here. Please note that I have not (yet) tested this unit for correctness or performance, and do not take any responsibility for the code.

Usage 
Usage is identical to that of FastSharemem.
