Hi Dave,

Sorry for the delay in answering this, I've recently been bitten by the
same problem and I've found that setting SYS:*TEMPORARY-DIRECTORY* to
NIL (or to something else) unconfuses Allegro CL. As soon as it has been
set once, SYS:MAKE-TEMP-FILE-NAME is should never be confused again, and
should follow the algorithm described in:

   http://franz.com/support/documentation/current/doc/operators/system/temporary-directory.htm

So swank-allegro.lisp should function correctly and the variables you
suggest are provided by Allegro themselves.

Did you follow up with Franz on this problem?
