Garbage Collection of FileWrapper

[GoogleCodeExporter]

fs.filelike.FileWrapper seems to have a garbage collection issue due to a 
circular reference together with a __del__ method. See attached script for a 
test. It will require the fs.ini file in the working directory. I have also 
attached a reference graph created by the objgraph module.

Sorry, attached the wrong graph file

I think that's a bit of a hack used by the opener system (in opener.open), and 
not a problem with FileWrapper per se.

I'll think about a workaround...

Checked in a fix to trunk which seems to solve this. No nodes in the
