[9fans] Passing a file descriptor between processes

[Kirill A. Shutemov]

One of the ugliest interface in Unix is passing a file descriptor between
processes [1]. Does Plan9 provide any mechanism for it?

You can pass fds in channels between threads, but for processes you
should look at #s for guidance.

i wish #s had a directory structure and enforced group permissions.

 Currently, if your processes have a common parent, you can use rfork; if
 not, you must resort to #s. '#s' is a pretty unfortunate interface,
 though...

 okay, practicially speaking, what's wrong with #s, and what do you propose?
