It causes frequent wakeups that waste power and prevent CPUs from entering a deep idle state. They also generate unnecessary traffic for the IPC mechanism so if every program decided to poll for something once a second, services like DBus would likely get hosed. -- Patryk Zawadzki ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Bluez-devel mailing list Bluez-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/bluez-devel
