If you remove the flush it seems to work *much* faster.
This might be a bug in core.  I'd probably report it.


I think to avoid the slowdown with reads you can "hack a work around" 
like

c = File.open('out.file','rb') { |f| f.read }
c.gsub!("\r\n", "\n")

But there might be a bug in there, too. [1]
