excellent! =A0i think you will find that plan 9 lends itself to this<= br> sort of work. =A0you are certainly welcome at any time to join plan 9
development.

the key here is to work out how to keep the existing lock api.
this is described here: http://www.9atom.org/magic/man2html/9/lock
i've prototyped this in user space, but did not get any further.

as for gsoc, please do submit an application. =A0there does happen to
be another student interested in MCS locks. =A0so we may need to
work out something to avoid having to pick between two good
applications. =A0but i am confident that we can figure this out as
things move forward.

if you have any more questsion, please ask the list, or contact
me off list via email or g+.

cheers!
