AutoLoader::AUTOLOAD optimization
I notice that although *.al are right alongside autosplit.ix the
trick AutoLoader::import uses to speed looking for the latter
is not used to find the *.al files - anyone know why?
On NFS mounted file systems at least, all the failed stats/opens are expensive.
(Sadly I am testing this at home where everything is local...)
