ok, I need to spelunk more into the latest linux syscalls. There's a whole new world of dirfds now available to make manipulating mounts much more flexible than using mount(2) https://manpages.debian.org/unstable/manpages-dev/open_tree_attr.2.en.html
how am i just running across Linux's preadv2/pwritev2 just now? they seem to allow non-blocking disk i/o without pthreads via RWF_NOWAIT! https://manpages.debian.org/testing/manpages-dev/preadv2.2.en.html#RWF_NOWAIT

@nprofile1q... @nprofile1q... that does make sense; translation for Linux binaries via binfmt_misc seems low overhead to keep around. I think I'm just enormously grumpy at the lack of macOS namespaces rather. Linux VMs shouldn't be imposed _by the vendor_ of the other OS!

@nprofile1q... writing's on the wall for that too, I suspect... the Virtualization.framework itself is surprisingly slow and buggy. Surprising because it was meant to be the modern ARM replacement for the Hypervisor framework, which was pretty solid on Intel!
