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

[Jason H]

This has been brought up before.

I believe it was decided that it was not a bug, that the behavior is whatever the OS services provide. 

From what I can tell you should have 2 signals below, as the file is closed twice.

I tested this behavior on Windows, Linux and Mac OS X.
It seems that this weird behavior is only on Mac OS X.
