Subject: Re: Suggestion for a new system call: convert file handle to a cookie for transfering file handles between processes.

Do unix(7) sockets with cmsg(UCM_RIGHTS) not give you what you want?

You can have a cookie process sitting in user space waiting on a UNIX
socket. When somebody passes you the right cookie string, you send them
a file descriptor.

P.S. I had to look a bit for cmsg(UCM_RIGHTS). I was more familiar with
     ioctl(I_SENDFD), which it appears that Linux does not implement.
