what, exactly, is a "MAGIC PID"? is this a change in the priority/nice level? pid's, in general, are assigned on a rotary (more-or-less) basis. has some kernel hack set aside a block of actual pids? this seems odd. so then, what is being changed in /dev/kmem? priority? nice? pid?
MAGIC PIDS are conceptually the same, in many respects to uids - ie the MAGIC UID is obviously 0. Theres a bit more flexibility involved, its possible to specify which tranche of pids have a magical quality. Vendors will have to support MAGIC PIDS, for the forthcoming additions to POSIX compliance.
