There is also some networking code as part of the smbfs. I don't
pretend I understand it completely - I worked on making it compilable
at this moment :) It uses some "spinlocks" and looked like it could
just use lockmgr(LK_SPIN). On the second read, it seems like it's
actually technically doing regular lock with tsleep(), i.e. equivalent
of lockmgr(LK_SHARED).
