As a developer whose most computation intensive job is Linux kernel compiling, I personally didn't suffer much from the dependency problem (priority inversion). :-) But I do believe swap-sched will be useful to the users who runs interactive jobs on a heavily loaded machine. If you are one of such users and have a success story with using swap-sched, please let me know!!!
Please also let me know what benchmark results you want to see. If you have done you own measurement for SWAP and want to share the results, send me email.
