[Interest] File change signal is emitted multiple times in QFileSystemWatcher on Mountain Lion (Qt 4.8.2)

[norulez at me.com]

Hello,

I noticed that QFileSystemWatcher is emitting the fileChanged() signal between 3 and 4 times.
Is this behavior wanted or is this a bug? Does anyone else has this behavior too?
How can i avoid multiple signals if this behavior is wanted?

How to reproduce:
1.) Create a file ("touch HelloWorld.txt")
2.) Open a file ("HelloWorld.txt")
3.) Modify the file ("echo "Hello World" >> HelloWorld.txt")
4.) The fileChanged() signal is received multiple times

System: Qt 4.8.2
              OS X Mountain Lion

Does anyone know when Mountain Lion is supported? Qt 4.8.3? Qt 5.0?

Thanks in advance

Best Regards
