For reference, this is how I implemented the same idea in JK2MV:

https://github.com/mvdevs/jk2mv/blob/master/src/qcommon/qcommon.h#L359-L372
https://github.com/mvdevs/jk2mv/blob/master/src/qcommon/vm.cpp#L850-L991
https://github.com/mvdevs/jk2mv/blob/master/src/server/sv_game.cpp#L343-L1088

Probably not all of these helper functions would be needed in ioq3. On first sight the main difference seems to be that it also sanitizes reads.

I can port it to ioq3 if you're interested, but it would be nice to get an extra review before doing so (it has been out in jk2mv since June last year and no reports so far).

This is being worked on in #441.
