I have often thought that processes should include standard control
file descriptor instead of argument lists and environmental
variables. So each process would have (initially) 2 inputs and 2
outputs. I think this is user level streams, but I've never seen it
done in a shell. Could standard control also give the process a
stream of capabilities? Here's my picture of how this might be
pp2.x3d The magenta spheres are commands and the cylinders are file
descriptors. Color signifies input or output for the file descriptors.
stdcap or stdctl anyone?
