It doesn't work on Android, and I can't fault it for that (Platform difference)
but it also drags in `uom` which has a bunch of template magic that takes
forever to compile, and I'm pretty sure it's dragging down my compile times.
I tried to build `ptth_server` on nightly to get compile timings, and heim
depends on `socket2` which failed to compile.
And I never ended up using the CPU monitoring. So heim is gone now.
