Does anybody have an idea on how to prove this? I don't know in what shape DTrace is (it's not enabled in amd64/arm yet, is it?), but the function boundary tracer might be of advantage here. It's not, but it should be... To enable it, build with `options KDTRACE_HOOKS' in your kernel config and `MKDTRACE=yes' in your mk.conf (or on the build.sh command line: `-V MKDTRACE=yes'). Then a basic thing to do for starters is dtrace -n 'profile-97::: { @[stack()] = count(); }' and ^C when you've done some file system operations to see the profile.
