Problem

- define a filesystem pickup (max connection : 10, max files per polling : 100, polling interval : 10)
- copy an input file in pickup directory
- when the file is taken into account, copy again the same file in the same directory
- repeat the previous step

The interval when the file is polled does not correspond to the polling time but it corresponds to "poll time *2" : if polling interval = 10 sec, the same file is polled every 20 sec

Resolution

* thats is the normal behavior. the internal de-bounce logic of the polling file system. We have to wait 2 polling cycles to see if the file is table (same timestamp and same file size) before we start consuming it; ie, move to the .ready folder
