0006 // Class TimeoutPoolOutputModule. Output module to POOL file with file
0007 // closure based on timeout. First file has only one event, second
0008 // file is closed after 15 seconds if at least one event was processed.
0009 // Then timeout is increased to 30 seconds and 60 seconds. After that
0010 // all other files are closed with timeout of 60 seconds.
