SMP TCP userland access

[Simon 'corecode' Schubert]

Hey,

while talking to a colleague this came up:

how does userland access to TCP connections play together with SMP and
TCP threads?  Is there still a lock?  Would it be beneficial if we lose
this synchronization and do it more DragonFly-ish?  I.e. will a
receiving process benefit from a different implementation without locks
(I've seen sblock() calls, so I guess it is still locked, dunno how this
plays into the TCP threads thing)

cheers
