mod_ruby : STDERR.reopen(STDOUT)

Hello,

How i can avoid to pollute the log of my web hosting with mod_ruby ?
I can put "STDERR.reopen(STDOUT)" at the top of all my web pages.
But i don't think it's a nice way, if I forget to put this line my web 
hosting
will not be happy.

Anyway with this line all errors has trapped (and warning). I can't see 
them in my .rhtml page
(but i have put STDOUT for reopen, so what's the problem ?)

Anybody know how i can see the error AND warn on my web page without
pollute the log of my web hosting ?

Regards,
