[Bf-committers] Why must sync selection be disabled to select UV islands?

[gandalf3]

Plus it doesn't work if you don't have seams (though admittedly most of 
the time this is probably not the case).

That reminds me, limit by seams doesn't seem to work for me. I mark all 
edges surrounding a bit of geometry as seams, then I select a vertex the 
middle, press Ctrl L and enable limit by seams in the redo panel. 
However the entire part remains selected.. Tested with 2.73a

Is there some trick to this that I'm missing?
