I tried to debug this myself this morning and haven't really found
anything yet.  However, SLIME's (or maybe AllegroCL's) behaviour at
the moment is really erratic and makes it kind of hard to work with
it.

For example, all of the stuff below happened in the SLIME REPL buffer
without the SLIME debugger popping up and without me typing anything
in between:

                       operating system will not make the space available
                       because the address space reserved for the heap
                       could not be increased.
