Yes i'm running current QT 4.7.4, and OS X 10.6.8. I have a simple test program
i can post if you have access to an OS X machine and want to look at.

the qt bug is not fixed. it really seems to be a bug (short fall) of OS X not
QT. eitherway, a process can't open more than 255 files without some system
manipulation which i wouldn't expect end users to do.

If you'd rather disable file watching, then go for it. I'm not familiar with
the file watching code and i wanted to make the smallest change possible to the
code to get it running on OS X.
