I believe you would see a different error.  EBADF occurs, if the file 
descriptor (i.e. the numeric value) is invalid.  You can provoke it by 
doing something like this

ruby -e 'File.open(10, "w") {|f| f.puts "test"}'

Whereas it does not happen if you do

ruby -e 'File.open(1, "w") {|f| f.puts "test"}'

One way to create this is to open a file, remember the number returned 
from #fileno, close the file and then open another file with the 
remembered number (file descriptor).

Kind regards
