That's cool - it hadn't occurred to me that metamath-knife could be run
single-threaded.   I believe, the command for this is:

metamath-knife --jobs 1 --verify set.mm


And oddly I'm not seeing any significant change in performance when I run
it.  Indeed, the only way I can tell the --jobs parameter is doing anything
at all is that I can slow it down by telling it to spawn an unreasonably
large number of threads.


    Best regards,


        Antony
