I've been noticing that several gnome-vfs apps randomly begin to use 100% cpu, and restarting the app is the only method of stopping it.

After some investigation, what appears to be happening is that in libgnomevfs/gnome-vfs-monitor.c actually_dispatch_callback() gets called and no_live_callbacks() returns FALSE, so install_timeout() gets called. In install_timeout, delay is 0, so it installs the idle timeout. This then repeats forever with the idle callbacks consuming the CPU.

I haven't figured out why no_live_callbacks doesn't ever return TRUE yet. Any suggestions on what to look for when debugging would be much appreciated.
