I'm not sure.  The only problem with going this away (and I realize this is
*extremely unlikely*) is that if the local setup, for whatever reason, has a
function defined that shares the identical name with a function in an unloaded
extension, a function_exists('foo') will return true even though the extension
is not available.  Don't know if this is splitting hairs too fine or not...

I don't have any benchmarking software set up at the moment, so if 
someone else
could see if function_exists() is faster, that would be great.
