Re: [Sawfish] High IO while config is open.

Ah, yeah, thanks.

Please excuse me if I now dump this here, but I have a hard time
figuring this one out. I have a 26MiB strace log just from ~15 seconds
running and tried to analyze it with all my might. Though, I feel like
poking into the dark...

Be warned, this is 26MiB+:
strace -txo strace_output sawfish-config
http://www.bonsaimind.org/tmp/strace_output

I have also attached the output of 'strace -c sawfish-config'. I can see
nothing too suspicious except these 'gettimeofday' and 'clock_gettime'
calls...which are quite often in my opinion. Writes do not seem to be
that frequent (roughly 320 calls), some of them seem to happen with
quite big packages, but it still doesn't look like that this would
explain the big disk activity I'm seeing.

I also did a clean install from git, same thing.

I'll of course look further into this...
