> The new unit test that tests periodic checkpointing fails on Windows. The problem is
that the method FSEditLog.purgeEditLog() uses renameTo() to atomically move edits.new to edits
> File.renameTo() fails on Windows is not atomic: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4017593
> I propose that we change this code to first try the renameTo(). If it fails, then it
deletes edits and then renames edits.new to edits.
