I think I can speak to Randall's plans for this.

Randall chose not to include in this commit the hooks for the default stack
to use the high-precision timers. I believe his immediate priorities are
upstreaming RACK and BBR. After that, if there is demand, he may upstream
the (relatively untested) code that allows the default stack to use the
high-precision timers (protected by a non-default kernel option) so others
can choose to experiment with it.

(By the way, we're hoping to change the terminology away from describing
the traditional FreeBSD stack as the "default" stack. In theory, someone
can make any stack be their local default. We'll need to figure out what to
actually call it at some point. My suggestion was the "FreeBSD" stack,
although that is lacking in some imagination. In any case, we should have
that discussion at some point in the future.)
