Hi,

every now and then i get the mysterious traceback with emacs and slime  
and i cant always figure out, how to detect the problem. In this case  
anonymous function is called with invalid arguments, but how do i  
know, what is the specific function, where it is and so on? This error  
comes, when using iolib tutorial socket server and while it talk about  
ccl threads, i thought if you could help with it:

Invalid program: Too many arguments in call to #<Anonymous Function  
#x30004108C64F>:
1 arguments provided, at most 0 accepted.
    [Condition of type CCL::SIMPLE-PROGRAM-ERROR]
