Hello again,

Here's a slightly better version that will handle the deletion of 
threads from the thread list correctly.

I've added the same things to my remote gdbserver version too, and the 
two are now working pretty much the same way on both Felix's test 
application, and my slightly more complex one.

Rgds,
John...
