I have this amazing ability to drop entire phrases from sentences!
The above should have read:
"Unix pipes do not run sequentially as Windows pipes do."
P2 will not sit idle until P1 completes unless P1 takes extra steps to
cause that behavior itself. Generally speaking P2 will see data as soon
as P1 flushes its output buffers (if using buffered I/O) or as soon as P1
sends a newline.
More or less.
