[clug] Thursday afternoon Perl/bash golf time

Because I like dragging old threads out....

I now happen to be writing python and am using Carlos suggestion below
to read binary data from a series of files, I now however want to
write this binary data to the STDIN of a subprocess call.

ie:

# do something magical to init the raw FD.
...

call(str(x) for x in cmd), stdin=raw)

for block in read_blocks(spoolfiles[start_spool_idx:stop_spool_idx]):
        raw.write(block)


Is there a "correct" way to do this in python? seems to be conflicting
information out there regarding subprocess.POpen and friends.
