Comment(by simonmar):

 `5975.patch` looks fine - I think the previous encoding/decoding was to
 handle Unicode filenames before we got support for them in the IO library.
 We should have a test for this too, though I'm not sure whether it will
 work to add a file with non-ASCII chars to the repo, it might be safer to
 generate one when we run the test.

 Good catch on the race condition.  I don't remember all the details here.
 It looks like exceptionFlag should be per-thread.  But if your patch works
 around it and all the tests pass then I'm happy for it to go in.
