Bug 780729 (SOA-3184)

Help Desk Ticket Reference: https://c.na7.visual.force.com/apex/Case_View?id=500A0000007pDhG&sfdc.override=1
Steps to Reproduce: 
The condition can be duplicated easily by cron'ing a script similar to the one seen below and using the helloworld_file_action quickstart.  (Start the ESB first, deploy something like the file gateway quickstart.  Use the script below to drop 600 small files each minute into the directory being watched.  The script will also grep the log for lines in the log as each file is processed.  You should see inconsistent line counts-- usually the number will be right for 600 files with 2 records, but once every 50 files or so you'll lose a whole file or at least a record from a file being processed.)

Further investigation will reveal:
- Sometimes an entire file just doesn't make it to the directory that holds the files after they are processed.
- Sometimes the file is processed for the first record, but the second isn't in the log.  In this case, the file will be in the 'processed' directory with the rest of the properly processed files.  

There were no suspicious log entries noted around the time of trouble.

Note:  Volume used for this test is identical to the customer's environment, 600 files per minute, 2 records per file.

The File Gateway occasionally loses a file (and also can lose just records from a file) under high file-count (but low record-count) conditions.
