[Openmcl-devel] native threads

[Tim McNerney]

My company uses Franz's SMP "Allegro" CL.  By no means am I arguing, but 
I also didn't know you could turn off SMP.
Of course you can use their old, non-SMP Lisp build, but who would want 
to do that, unless your code isn't SMP-tolerant?
We sort of lucked out because of the way we wrote our apps, so we can 
safely translate WITHOUT-INTERRUPTS to PROGN.
