Has anyone detected signs of life recently at Digitool (makers
of Macintosh Common Lisp)? I've been trying to reach them
for more than a week. E-mail goes unanswered. The telephone
goes unanswered. Are they working WITHOUT-INTERRUPTS?

I bet they are. Typical lisp people, using without-interrupts when
they should be using a lock. They'll never run on multiprocessors.

Digitool knows the difference. MCL has LOCKs built-in and
they are extensively used for example in CL-HTTP.
Also MCL has CCL::IGNORING-WITHOUT-INTERRUPTS . ;-)
I guess Digitool is currently working without using
CCL::WITH-SHOWN-PROGRESS.
This brings me to some other trivia. My favorite MCL
function is: CCL::MAKE-PROGRESS . ;-) I like to
make progress. I'd like to have a portable version,
though.
