I have a hard time believing that you cannot dump stats for a readonly 
file. Anyway im dumping to stdout not a file, just to make sure that 
there are no misunderstandings there.

btw. I have this behavior both with and without irb and both on
ruby 1.6.7 (2002-03-01) [i686-linux]
and
ruby 1.6.8 (2002-12-24) [i686-cygwin]

any ideas? (i'd rather not update to 1.8 - at least not before 1.8 comes 
out of it's "pre" state....)
