Sorry, I didn't read it, yet. I'm doing it now, but consider that I will 
be on vacations for
the rest of this week :(

To be clear: I did write that testcase, but only following existing 
practice, as far as timing issues are
concerned. I'm still hoping to comment in a technically sound way, but 
in the meanwhile, I'm afraid
too many people are experiencing annoying time-outs.

Maybe, for the time being at least, you can just go ahead with your 
fixes to the testcase. As soon as
I'm back from my vacations, I will actually double check that the 
testcase is still testing what it should.
Or maybe you can do that? Would end the story...

Thanks,
Paolo.
