I'm currently working on a Python audisp plugin. My main routine

while True:

While profiling my plugin, I noticed that 95% + of the CPU time used by my
plugin is used in fileinput.input(), waiting/reading from input
Is there any way to lower this or preferred way to poll/read?
I don't do much if any python programming. But in C, all examples include a
select in the event processing loop. Python has a select module. There are
examples on the internet about how to use it. One is here:

There are other examples.
