sending messages, user process <--> kernel module

[ibotty]

recently there was a question on freebsd-hackers, on how to send async from
kernel to userspace (and vice versa).

is our leightweight messaging able to do this (with only moderate work
needed)?
according to the lwkt_ prefix it is not intended.

but as lwkt messaging has been ported to userspace...

btw: i am aware of other possiblities, i am just curious, whether this is
possible.
