The reason I haven't done logger yet is nothing specifies what the log  
levels should _be_. Posix says:

Which is almost useless as a spec.

You've hardwired in a dozen plus names, including a bunch of local#  
names which don't seem particularly advisable. Those names do _not_  
include three of the four android ones:

That has "main", "events", "radio", and "system", hardwired into the  
kernel. (And uses a different mechanism to write to them, each with its  
own /dev node going into a separate kernel buffer.)

Hmmm, I've thrown it into pending so I don't lose track of it, but  
there's pending design work here.
