This looks like a bad idea; with SVR4 we have a more or less standardized solution for local ipc, so it's better not to touch it. hasty> This is another area which if its implemented properly can boost hasty> the performance of the server, some claimed by a factor of two hasty> for certain operations. I am very skeptical about this; for small messages the overhead of using streams is not important, and otherwise, for large messages, support of the SHM extension is built in, so it's already there. -- Piercarlo Grandi | JNET: pcg@uk.ac.aber Dept of CS, University of Wales | UUCP: ...!aber-cs!pcg Penglais, Aberystwyth SY23 3BZ, UK | INET: pcg@aber.ac.uk
