You would need a lock too, which makes the stack superfluous. But I
think you're making it too complicated. Making the parameter arrays
local to the process/thread is easy, simple and also proven. Take a look
at Andreas Kromke's mt_gem-lib to see how easy it can be done. It's also
100% compatible with TOS and MagiC.
