Just to clarify: this is not a limitation of the Qt implementation on OS X
(iOS), but really a limitation (by design) of the underlying Cocoa.
And yes, having a Qt event loop running in a thread other than the "main"
thread /does/ work on Windows and Linux (possibly/likely other Unix) - just not
on OS X/Cocoa.
Here's a link for starters:
