To enforce the Slime debugger you could use swank:simple-break instead
of break.  

I don't use OpenMCL myself, but after reading the code in
swank-openmcl.lisp I'd say that BREAK invokes the Slime debugger only
if it is called in the REPL thread.  There's even a variable
*break-in-sldb* to customize this a bit.  We should probably add one
more option so that sldb is invoked in all threads.  If a OpenMCL user
posts a patch for that, I will gladly commit it.
