[trivial-timeout-devel] clozure cl doesn't recognize dynamic variables

[Milan Jovanovic]

Code enclosed with WITH-TIMEOUT on CCL runs in separate thread and  
this behavior is correct and documented (regarding threads and dynamic  
environment), SBCL threads and dynamic environment works the same but  
WITH-TIMEOUT on SBCL is implemented on top of SBCL timers.
This is probably  bug in trivial-timeout context but i don't think  
that there is easy&good solution here ...
