Discussion with Chris on #poe led me to experiment with a non-streamed 
version (which is only a little bit cheating)

	http://balker.dk/simplehttp2.pl

which gave me some insight:

Starting the script without the foo.txt file in place, every new concurrent
wget of the file (within the five second window currently in place) would
lead the new event to override the old one, as per the debug output printing
out the response-objects wheel-id.

I assume this is much the same problem as with the streamed version of the
script.
