I think fxp in the former times made use of ZERO_CPOY_SOCKETS. I also=20 have some private boxes arround with re and rl. I haven't had any SSH session stall with the tonight MFCs to RELENG_8=20 yet on my Hartwell box. All others were fine besides the jumbo frame testings. So I guess ZERO_CPOY_SOCKETS doesn't play a role, most likely your code from=20 -current is just fine.
