Description Michael Meeks 2005-09-07 09:20:36 UTC 
So - my machine is sitting idle - no files changing, it has been running all
night. Beagled should be doing nothing, and indeed strace shows it's not doing
anything substantive - however it is chewing my battery, using 0.5% of my CPU
doing essentially nothing (trace attached). It seems 'Best' is doing similar stuff.

Is this a Mono problem ? why do we need a busy loop here ? can we not wait on a
condition in the worker threads & block in poll in the mainloop ? - surely we
shouldn't be burning CPU & laptop batter to not do anything ?

This patch should at least help.  AFAICT this was the only place in beagle that
we were polling.
