I am using aserve under cmucl and call the INIT-ASERVE-CMU function as the README suggests (otherwise latency is unbearable). INIT-ASERVE-CMU looks like this:
#'(LAMBDA () (BLOCK INIT-ASERVE-CMU (UNLESS (FIND-IF #'(LAMBDA (ASERVE-SYSTEM::PROC) (STRING= (MULTIPROCESSING:PROCESS-NAME ASERVE-SYSTEM::PROC) "Top Level Loop")) (MULTIPROCESSING:ALL-PROCESSES)) (MULTIPROCESSING::STARTUP-IDLE-AND-TOP-LEVEL-LOOPS))))
After running it slime-space no longer shows the arglist. This is slime HEAD.
Tried it under sbcl-mt. Naturally, since init-aserve-cmu need not be run, everything works fine. I may even use it but compilation notes do not work and I'd miss them very much.
