file based queues

[Eric S. Johansson]

seems to me this would be a fairly obvious component to be part of the 
Python repertoire but I haven't found any yet.  I want to store objects 
persistently and have the underlying object behavior be that of a queue.

usually, this is implemented as a series of files within a directory or 
directory hierarchy but I'm not fussy.  Just as long as it doesn't have 
much overhead like mysql or twisted.

any suggestions?
