Yes it is. That's a result of two things:
1) The people who invented pipes were *very* smart (but not smart
enough to invent stderr at the same time :-).
2) Pipes use a dead simple concurrency model. It isn't even as
powerful as CSP. No shared memory. No synchronization primitives. Data
flows in one direction, and one direction only.
Basically, each element of a pipe can be programmed ignoring
concurrency. It doesn't get much simpler than that.
