Take a look at geom_gate from Pawel Dawidek. You could probably very easily modify the client side to do your own code, instead of passing it over the network to the server. http://garage.freebsd.pl/geom_gate.README > What would happen if the kernel decided to swap out such a process? Probably a deadlock... you could partially avoid this by using mlock to prevent your process from swapping. It may still be possible to dead lock due to the stack of the process being able to be swapped out.. some one better versed in the process/VM interaction should answer that. -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not." _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
