I'd prefer if we have a single ultimate name resolution function,
instead of doing function 5 now, and function 6 later, when we have
dealt with the malloc matters.

One way to deal with the dlmopen/static dlopen issue would be to define
a deallocation function which goes with the 5 function.  If this
function called free, it would automatically end up at the right definition.

Thanks,
