Subject: mmap() in an extension blatting $stdin ?

I wrote an extension which mmap's a binary file for extensive
frobbing and, somehow, it blats my $stdin and ARGF.

  rjp> less test.rb
  require "extension"
  
  a = Extension.new("moo")
  
  ARGF.each { |i|
  	p i
  }

If I do "ruby test.rb < file.txt", or otherwise try to pipe something
into $stdin, I get the contents of my binary mmap'd file.

If I do "ruby test.rb file.txt", I get the contents of my file.

Removing the "require" and "Extension.new" lines makes everything fine.

Has anyone seen this kind of weirdness before?
