I really don't see a problem if we make sure that at a later date we revisit the issue and ask for another window to be reserved for our usage. Let's accept this for the time being and update our syscalls.master to remind people not to infringe upon the BSD/os reserved syscall space. -- -Alfred Perlstein [alfred@freebsd.org] Ok, who wrote this damn function called '??'?
