if it's really a pipe you can write 0 to have it read 0.
just keep that up until it goes away or you become bored.

A reason to close one direction of a pipe is if the program
at the other end of the pipe is a filter (think "ssh system command")
and you need it to see EOF before you can be sure of getting
all its output back in the other direction.
