The default open mode is 'w+', so append occurs at file pos = 0.
So, like an existing file, your init. string gets overwritten.

     try StringIO.new("text", 'a+')  # or 'a'

 (Not defending, just observing ;)


Aside:
StringIO in CVS  ( ruby 1.9.0 (2004-04-27) [i586-bccwin32] )

#-----
require 'stringio'

sio = StringIO.new
STDOUT.reopen(sio)
#-----

C:/TEMP/rb5226.TMP:5:in `reopen': cannot convert StringIO into String (TypeError)

(I appreciate IO#reopen is undergoing changes; thanks)
