That's precisely the bug in the mknod() system call: you cannot specify the
owner! :-(

\Other side of the question:  Why doesn't this hole appear when files
\are created?  Or does it?!?
\-- 

Files needn't be created by mknod(): there's creat() or open().

Is there no darkness in Iran, Chili, South-Africa, Auschwitz, etc. etc. ETC.?
