/**
 * Helper method to avoid a known Java File.renameTo issue on Windows.
 * File.renameTo appears to intermittently fail on Windows. We retry a few
 * times after sleeping briefly. A day long experiment shows that in a
 * scenario where renameTo is known to have intermittent failures, that we
 * retry at most once, at which point it succeeds. The scenario where rename
 * has failed is when renaming the slot 2 file to slot 1 in the positionFile
 * method (note, we've never seen rename fail in the recover methods which
 * also does a rename of slot 2 to slot 1).
 *
 * Interesting notes to consider - we've never seen renameTo fail when
 * renaming slot 3 to slot 2. The slot 2 file is never opened for read or
 * write. The slot 1 file is only ever opened for READ. The slot 3 file is
 * only ever opened for WRITE. SEE TEE.TFSPREVIEW BUG 4184 for more info.
