Danny,

It is now written and will be in the next lisp.mac (alice currently
has a hold on the file for a bug fix).
I made one change.  The fns take a 3rd arg, FLG.
If FLG=non-nil then NEWFRAME will be released if the change succeeds.
eg, if you want to do the smash and release all the stack pointers,
put still catch things if the smash fails, you could say

(if not (RELSTK (SETALINK FOO FUM T)) then (SMASHLINKERROR FOO FUM))

or some such.

Daryle

p.s. A test case I was using was setalink[foo;fum] followed by
setclink[fum;foo].  How's that for a case of lisp incest?
