I forgot, but I removed the error case of with-cast-pointer from uffi, as I 
need it to run my code.  (I didn't know it was expensive on SBCL, but right 
now I am more concerned with functionality than efficiency.  Besides, I last 
time I looked SBCL didn't support callbacks, which is something I need to get 
things working.)

Also the hanging/deadlock still persists.
