How to do spliced pipes:
	cmd_a > file; cmd_b <{ cmd_c < file} <{ cmd_d < file }
can also be done as:
	cmd_b <{ cmd_a | cmd_c} <{ cmd_a | cmd_d }

But if "cmd_a" is heavy, how can this be done without running it
twice, or using a temporary file?

Alternatively, is there an easy way to do named pipes in rc?

Thanks,
