Breaks cross-platform, specifically Macs swallow silently. stat just works

I don't believe this to be true.

  • See comment below - Darwin silently drops same-process notifs. I could change the behavior depending on same vs cross process and platform but I wanted to”just one thing to worry about”. Potentially a good optimization later. Would help reduce syscalls.

    • I have no idea why they aren't using kqueue but that works on macOS and FreeBSD. It has for years.

      You want EVFILT_VNODE with NOTE_WRITE. That's hooked up to VNOP_WRITE in the kernel, the call made to the relevant filesystem to actually perform the write.
