Upgraded from 8.04 to 8.10 and found a high load average and huge numbers
of "polkit-read-aut" called from "hal-acl-tool" in my lastcomm logs:
# lastcomm | grep "Apr 14 20:46" | wc -l
9772
# lastcomm | grep "Apr 14 20:46" | grep -c polkit-read-aut
9591
# lastcomm | grep "Apr 14 20:46" | grep -c hal-acl-tool
32
The command line is actually "hal-acl-tool --reconfigure" which calls
polkit-read-auth-helper (over and over and over!).
To slow this down, I replaced /usr/lib/policykit/polkit-read-auth-helper
with a shell script that dumped some environment into a file and did a
"sleep 1" before calling the real binary (renamed to "polkit-ian").
That sleep slowed things down and helped the load average a bit:
# lastcomm | grep "Apr 15 20:40" | wc -l
539
#~[10127] lastcomm | grep "Apr 15 20:40" | grep -c 'polkit-ian'
59
# lastcomm | grep "Apr 15 20:40" | grep -c 'hal-acl-tool'
3
but now I get "X" entries beside all the hal-acl-tool calls:
# lastcomm | grep hal-acl-tool | wc -l
2364
# lastcomm | grep hal-acl-tool | grep X | wc -l
2364
# lastcomm | grep hal-acl-tool | grep X | head -2
hal-acl-tool X root ?? 0.01 secs Wed Apr 15 20:44
hal-acl-tool X root ?? 0.01 secs Wed Apr 15 20:41
I modified my script to run an strace of polkit-read-auth-helper to see
what it was doing 9,772 times per minute and here's one of those dumps:

Where do I start trying to debug this looping problem?
I am *not* running Gnome or GDM. I use vtwm via "startx" after I log in.
