Also, its would be helpful to be able to see error messagea when they 
happens, but Im not quite sure how to get the lisp code called by the 
foreign process to print in the lisp terminal when an error happens. 
Sometimes, when I get an error, OpenMCL notifies me that a process is 
attempting to write to the terminal, but the message itself is not 
visible. Ive tried several things with *terminal-io* inside the 
callback code  but im afraid Im just stabbing in the dark, do i need to 
lock it somehow, or use someting like with-terminal-input but for 
output? Any advice would be appreciated!
