Herp derp... yup that was the error I made. So the remaining question - whether it would be good to swap SYSVSEM with PROC_PTHREAD on linux - should be based on more study, Jim's performance question first and foremost, and also observations about similar projects and the intrinsic flaw of lingering semaphores after abend. It may be worthwhile to note that my default FC25 box has zero sysv semaphores during normal operation, which suggests it is greatly avoided.
