"failed to setup shm segment" on macOS Monterey with ipcs empty

[Rebecca Cran <rebecca@xxxxxxxxx>]

I just tried to run fio (from master) on my new M1 Max MacBook Pro 
running macOS Monterey. "./fio examples/tiobench-example.fio" quit with 
the error "failed to setup shm segment" but "ipcs" doesn't show any 
entries, so it doesn't appear to be the typical problem of left-over 
segments.
