Hi,

What's the problem?

Just wait as long as you can accept to be "late" when your file changes.

So if you can accept e. g. 5 seconds delay, you'll change Lane's example to:

time=os.stat(file)[8]

# analyze data

while 1:
	if os.stat(file)[8]>time:
		#analyze data again
	else:
		time.sleep(5)


This will drastically reduce your CPU load ;-)
