-FIXME/TODO list

-This is a list of open issues for H4 node
-
-1) Locking/SMP
-
-	External code now uses ng_send_fn to inject data into Netgraph, but
-	i still use splXXX to lock tty level. this is wrong and should be
-	fixed!

- ** allows access to the device via the "hook" hook of the node.
- **
- ** Once the line discipline is installed, you can find out the name of the
