That is the way I currently have it set up.

There is one thing I don't understand about the F packet. How does the
inferior know that it is OK to send the packet. From everything that I
have read. Comunication is initiated by GDB and answered by the
inferior. I didn't know that the stub could initiate a packet. If so, Do
I just tack on the F packet information to the end of a currently
generated packet?

This is the reason I was polling. Otherwise I prefer to not poll.

I think I have answered this by answering the preceding question.

If I implement the F packet would that get rid if the need for a xxx-shlib?
