Bug Description

I get an error when I am trying to run Swift-recon-cron:

ile "/usr/lib/pymodules/python2.6/swift/obj/replicator.py", line 611, in run_forever#012 self.recon_object)#012 File "/usr/lib/pymodules/python2.6/swift/common/utils.py", line 1110, in dump_recon_cache#012 raise#012 File "/usr/lib/python2.6/contextlib.py", line 34, in __exit__#012 self.gen.throw(type, value, traceback)#012 File "/usr/lib/pymodules/python2.6/swift/common/utils.py", line 672, in lock_file#012 yield file_obj#012 File "/usr/lib/pymodules/python2.6/swift/common/utils.py", line 1104, in dump_recon_cache#012 os.rename(tf.name, cache_file)#012OSError: [Errno 18] Invalid cross-device link

After researching it seems related to have a non atomic linux config and having /tmp on a different partition/filesystem
