Why do we have to check the args (ask I while demonstrating my LAP ignorance)?
Commenting out (check-nargs 0) hasn't made any effect that I can see yet.

Re. process-preset, your demo code does not crash for me Terje.

Nor does (process-run-function "Seldom Starts" (lambda ()())) Ron. 
Though that does seem to highlight inefficiencies (presumably 
Rosetta):

(LOOP REPEAT 100 DO (PROCESS-RUN-FUNCTION "Seldom Starts" (LAMBDA NIL 
NIL)) (SLEEP 0.1)) took 25.583 seconds to run.
Of that, 25.109 seconds were spent in The Cooperative Multitasking 
Experience. (which seems high - CLZ (Clozure) takes 10.6 seconds).

(loop repeat 1000 do (PROCESS-RUN-FUNCTION "Seldom Starts" (LAMBDA 
NIL NIL))) did hang.

Will experiment to try to discover what I can get to make it crash 
consistently.

Anyway, suggestion: that we detail with our posts the context in 
which we're doing anything on RMCL.
Here I'm running vanilla RMCL with rmcl-clos-patch on MacOS 10.5.7 on MacPro.
