I am not sure if it was completely fixed. (This was related to a Lucene bug)
But you can try w/ a recent build and confirm it for us.
I have never encountered these during our tests in windows XP/Linux
I have attached a patch which logs the names of the files which could
not get deleted (which may help us diagnose the problem). If you are
comfortable applying a patch you may try it out.
