DrScheme has a form
(object-wait-multiple timeout thunk)

which returns #f is thunk fails to return within timeout secs, or 
returns the value of thunk

are there any similar constructs in openmcl or sbcl?

thanks

Ugh. What if the thunk returns #f?!?

SBCL has WITH-TIMEOUT. Dunno about OpenMCL. Tried (apropos "timeout")
yet?
