Thank you Oliver. I have a couple more questions if you have a second:

What are you returning from init_mex()? Is that a pointer to a C++ class instance? If so, how are you allocating the memory, are you using "new" or "mxMalloc"?

Please excuse the double-post, sorry about that.

I haven't gotten round to implementing it myself, but I plan to return a pointer to a C++ class instance (cast as a uint64), with memory allocated using "new". MATLAB will call the myclass delete function when it clears the pointer, so the only time this wouldn't happen is if MATLAB crashed. However, in that case I'd hope that the OS' memory management system would free all the memory associated with that thread, including the memory allocated by "new".
