btpand uses a lot of CPU

[Daniel O'Connor-3]

Hi,
I have btpand working OK, however I notice that it uses a lot of CPU
(20-70% of a Pentium-M 1.4GHz) even when idle.

hcidump doesn't show any untoward activity and I'm not sure how to go
about debugging it..

perhaps it is looping?

You could build it with -DEVENT_DEBUG and enable LOG_DEBUG messages in
syslogd.conf that might show more information..

What system version do you use? There was a bug causing high CPU usage
fixed few months ago.

Ah yes, it is a bit stale, I updated event.c and now it's all good.

Thanks!
