Comment 71 for bug 36581

gamin-0.0.14-1, current rawhide, x86_64 dual opteron.
Output from SIGUSR2 shows it's looping through the following list of
files. Looks like a poll_file loop is stuck. Quick source read
points at gam_poll_scan_directory_internal and the for loop:

  for (l = children; l; l = l->next) {

Poll: poll_file for
/usr/share/applications/gnome-accessibility.desktop called
 at 1097770113 delta 0 : 0 Poll: poll_file
/usr/share/applications/gnome-accessibility.desktop unchanged
1097700841 0 : 1097700841 0
Poll: poll_file for
/usr/share/applications/redhat-neat-control.desktop called at
1097770113 delta 0 : 0
Poll: poll_file /usr/share/applications/redhat-neat-control.desktop
unchanged
1096989180 0 : 1096989180 0
Poll: poll_file for
/usr/share/applications/redhat-rhn-up2date-config.desktop called
 at 1097770113 delta 0 : 0
Poll: poll_file
/usr/share/applications/redhat-rhn-up2date-config.desktop unchanged
1095979273 0 : 1095979273 0

And gdb confirms this:
