yes, should be possible. I am often connecting different debug clients, also 
while changing for example the preferred gateway or the gateway-class.

Do you feel this problem has arised with a specific revision (has it been 
there with rv1069 and before) or has it always been there and your setup has 
changed?

Actually not. Unfortunately I'll be probably be offline during the next week 
and cant do much. There is a completely thread-free version waiting to be 
checked in, then we can see if this helps, But actually I would prefer to 
nail down the source of the problem...
