+  * notice: The implementation of MAP-ALLOCATED-OBJECTS (the heart of

   * enhancement: RUN-PROGRAM supports a :DIRECTORY argument to set
     the working directory of the spawned process.

   * enhancement: "fixed objects" can now be stack-allocated on PPC.
   * enhancement: WITH-PINNED-OBJECTS no longer conses on PPC/GENCGC.
   * enhancement: (sb-introspect:find-definition-sources-by-name x :vop) now

     of quadratically with the size of the input in the worst case.
