There are two reasons I'm showing you this screenshot. The other one (besides that the McCLIM Listener looks really cool and any excuse to take pictures of it is a good one) is that it's (i) running in SBCL, (ii) running usably fast, (iii) not eating all the CPU in an idle loop.

Ingredients: an SBCL that understands SB-FUTEX, running on a Linux kernel that supports futexes. A McCLIM patched with this patch (and see this message as well for the context). Some random frobbing.

I sort of wrote a condition variable implementation for CMUCL as well, but it's utterly untested - and frankly, unlikely to work, given that despite lying in bed this morning for three hours carefully doing nothing I still didn't actually get any sleep.
