[avahi] avahi-daemon periodically eats CPU 50% more or less in embedded system

Hi, there,
I'm recently working on porting Avahi (version 0.6.22) to an embedded Linux
(kernel 2.6.17) platform. The job is almost done and we already achieved all
the functionalities we want. However, during further testing, we found in
some lab that there are heavy Bonjour network traffic (many Mac OS hosts),
Avahi-daemon will eat CPU time periodically.
We use strace to find what is happening, and here is the data, seems like
the timeout value which avahi calculated for next poll operation is always 0
for a while, not sure whether that's expect behavior and whether such tight
poll loop eat CPU time. Also want to mention that, after we plugged out the
network cable, the symptom disappear, after plugged in back, appear again.
Even after kill avahi-daemon and restart it, problem is still there.
Any help we can get from here? Thanks in advance!
