No, this is not a bug in pipes, processes are supposed to run in
parallel, that't the whole idea. Think of a very very big input stream
that you want to run grep over, you really don't want the pipe blocking
until the process providing the input stream has finished, you might not
even have enough memory to hold the entire stream. And waiting for the
first bits of data through the stream hardly helps either, because that
just means that the file will be overwritten when the process providing
the input stream has only read it partly. So, yep, a pipe dream. ;)
