For some time now kio_http_cache_cleaner has been making me mad by generating
huge io in the background running on the least favorable ioniceness (should I
say iobadness) regardless of other heavy io jobs, or the laptop being on
iotop gives me the following:
Total DISK READ: 656.84 K/s | Total DISK WRITE: 0.00 B/s
TID PRIO USER DISK READ DISK WRITE SWAPIN IO> COMMAND
16484 be/4 christop 656.84 K/s 0.00 B/s 0.00 % 98.51 %
1 be/4 root 0.00 B/s 0.00 B/s 0.00 % 0.00 % init 
2 be/3 root 0.00 B/s 0.00 B/s 0.00 % 0.00 % [kthreadd]

4 be/3 root 0.00 B/s 0.00 B/s 0.00 % 0.00 % [ksoftirqd/0]
My cache size is 51200 (I guess KB) which should be KDE's default.
Do others experience the same problem? Any hints on what to do about it?
"killall kio_http_cache_cleaner" is my little friend and helper right now. I
can't see any artifacts from not running the process every once and a while,
so I guess there is no need for my hard-drive being bogged down that often.
