its block, not lock, and one uses file.flush() after using file.write(),
so the stdin is the wrong side - you have to push, you can't pull..
Here is the unblock function I use - it comes from the internet,
possibly from this group, but I have forgotten who wrote it.
# Some magic to make a file non blocking - from the internet
def unblock(f):
"""Given file 'f', sets its unblock flag to true."""
fcntl.fcntl(f.fileno(), fcntl.F_SETFL, os.O_NONBLOCK)
hope this helps - note that the f is not the file's name but the
thing you get when you write :
f = open(...
