Hi all.

Rails segregates 'framework' and 'app' files so the latter may be  
reloaded
per-request during development.  The result is a quick, responsive dev
environment, but it means Rails is going out of its way to implement  
a feature
that Ruby does not natively provide.

We can't tell whether two different paths refer to the same file so  
you'll
see double-requires depending on your load path.  You shouldn't see  
them in
the framework itself since it uses 'normal' requires.  Otherwise we'd  
hit an
inf. loop wrapping already-wrapped methods (as Ara reports.)

Unfortunately, I am unable to reproduce on 1.8.3 or .4p2 with Rails  
1.0rc5
running Linux or MacOS X.  I will try 1.8.2 + FreeBSD shortly.

Please note: there is a rails-core list for which this thread is well  
suited.
(I hope this error is not an issue with Ruby itself.)

Best,
