mkdirsWithRetry

public static boolean mkdirsWithRetry(File f)

A thread-safer mkdirs. mkdirs() will fail if another thread creates one of the directories it means to create before it does. http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4742723 This attempts the mkdirs() multiple times, so that if another thread does create one of the directories, the next call to mkdirs() will take that into account. Note: this returns true iff the file f ends up being a directory, contrary to mkdirs(), which returns false if it existed before the call.
