Please tune this to a smaller number.  (400?)  Injecting function pointers causes problems for asm (it reserves X function pointers for each possible function type, so it's inefficeint).  Down the road I'll need to rework the system to avoid using this parameter, but for the meantime it would be nice not to wildly overallocate the number of function pointers.

You should probably also add a comment to this effect, although I'd also be happy to do it myself later (I didn't realize this should be documented until I saw your change).
