Hi ,

The problem could be that FieldMonitor did not have enough time to 
"addFieldWatch" but the vm to monitor (TestPostFieldModification) was 
already ended.

So we should make sure that TestPostFieldModification exits after 
FieldMonitor has done necessary. The solution proposed here is that 
FieldMonitor creates a file after adding field watching, and 
TestPostFieldModification quits only after finding the file.
