For example, the info thread command lists the thread number, pid, and an info field (which in my case is the task name from the kernel task struct).  So how would a macro keep this info intact and display it along with the "up" result on the same line?  In my thoughts on this I have considered a maintaince request to the host which would return the pid and the info field, ....

Sorry, I'm lost here.  Can you perhaphs sketch out how you'd expect GDB, 
the user, and the target to interact?
