I probably cannot compete with your number of runs, but I also think 
needing to wait 5 seconds would be way too long ;-)

I fully agree to b) and to write classes in a way that they are well 
testable with unit-tests. I initially thought about making the 
timeout-setter private being accessible only by the unit-test. But as 
you say the interface also makes clear that there is a timeout. So 
making this public is fine for me (even if in Dolphin we rely only on 
the default setting).

Thanks,
Peter
