[JGIT RFC PATCH 3/3] Rate limit warnings spewed by RepositoryTestCase.recursiveDelete

[Jonas Fonseca <fonseca@diku.dk>]

On Windows XP / NTFS / NetBeans 6.1 / Java 5 a lot of warnings are
printed. In most cases the path is in fact deleted and it seems to just
be a timing bug or something Windows or NTFS specific. Also, many of the
warnings are for the same paths and therefore a bit redundant.
Furthermore, when a lot of warnings are printed it gives the feeling of
slowing down the tests. By rate limiting the warnings the problem is
still made visible for developers to notice.

 This is mostly an annoyance fix, but might be acceptable.
