that reminds me: new plan 9 users
might not be aware of the following way to use sam.
it works on plan 9 but also on some unix systems.

in my window system startup file,
i typically create one window of significant size in which i run sam.
that remains on screen until i log out (subject to `Hide' in 8½ or 9wm).
as i wander about the system in other windows, i use the B command (see sam(1))
to throw files into it for editing.

on slow terminals, the single sam instance can be invoked as sam -r $cpu.
using this method, you are also rarely bothered by windows containing
the remnants of an instance of sam.
