Sounds like the .close() isn't getting executed as you think. Try using 
the logging module to log a line immediately before each open and close 
so that you can ensure you're really closing all the files. 
Alternatively, some other bit of code my be the guilty party. A utility 
like fstat can show you who has files open.

Good luck
