If the poll is interrupted close to the timeout then it will restart the 
poll with the original timeout so it will be longer than it should. For 
the debugger transport I don't think this is a big issue as the timeout 
is only used in the initial handshake (if I remember correctly). It may 
be more trouble that its worth to fix this. As to how then gettimeofday 
could be used so that we get the elapsed time of the interrupted poll 
and that could be used to adjust the timeout. There are a couple of 
example in other places in the JDK.
