Ah, I meant bare CVS version. Carbon Emacs Package is also a modified

Thanks for testing.
The second thread seems to be spawned when one uses the file dialog on
Leopard. Carbon's Navigation Services (file dialogs) have heavily
changed on Leopard so it uses Cocoa's NSSavePanel/NSOpenPanel (you can
see the difference by typing `/' or `~'). So I suspect some bugs have
been introduced there. Maybe you can avoid this situation by setting
use-dialog-box to nil in the meanwhile.
I also guess high CPU usage has something to do with filesystems over
network, because SystemNotificationTaskProc above seems to monitor
file system volume and the socket monitor thread (the first thread
above) is also busy. Maybe you can monitor network packets while high
CPU load is observed.
