Bug#489260: dfm: auto-update uses close to 100% CPU
Package: dfm
Version: 0.99.9-1+b1
Severity: normal
after launching DFM from my .fluxbox/startup or command-line with
dfm &
CPU usage is fine at this point.
After about 40-45 seconds of almost zero CPU usage, the CPU usage for
DFM rockets up to heavy usage and stays there until the process is
killed. This seems to be related to the "40 second" update/refresh
period set in the DFM configuration. Before upgrading my version of
DFM, refresh happened at 40 seconds with no problems. Since the
upgrade, it has caused the heavy CPU usage. Changing the DFM update
frequency to 0 disables auto-update, and prevents the CPU utilization
from sky-rocketing. However, auto-update now seems to be broken.
I've tried leaving it for 5+ minutes to see if it would solve itself,
but it remains at high usage indefinitely until killed.

--------------------------------------------------
a check of the output of "ps axf" shows that the DFM process has no
child-processes, and is in the "R"unning state:
PID TTY STAT TIME COMMAND
18705 ? R 4:19 /usr/bin/dfm
The high CPU usage is also shown by wmtop which graphically shows DFM
with high CPU utilization.
