Hello everyone,
the discussion in -current and the behavior of my hard disk caused me to
investigate. Whenever kde programs are run on this system, the hard disk
will not spin down (even when excessive timeouts for syncs are in effect)
So I ran truss against kwallet and plasma-desktop to find out they do the
same thing:
stat("/home/erika/.kde4/share/apps/kwallet",{ mode=drwx------
,inode=56314,size=3,blksize=4096 }) = 0 (0x0)
clock_gettime(4,{10454.430272035 }) = 0 (0x0)
clock_gettime(4,{10454.430363671 }) = 0 (0x0)
clock_gettime(4,{10454.430432397 }) = 0 (0x0)
clock_gettime(4,{10454.430516490 }) = 0 (0x0)
read(8,0x808f9102c,4096) ERR#35 'Resource temporarily
unavailable'
poll({3/POLLIN 9/POLLIN 8/POLLIN 5/POLLIN},4,0) = 0 (0x0)
clock_gettime(4,{10454.430734403 }) = 0 (0x0)
read(8,0x808f9102c,4096) ERR#35 'Resource temporarily
unavailable'
clock_gettime(4,{10454.430882473 }) = 0 (0x0)
read(8,0x808f9102c,4096) ERR#35 'Resource temporarily

poll({3/POLLIN 9/POLLIN 8/POLLIN 5/POLLIN},4,499) = 0 (0x0)
clock_gettime(4,{10454.939752100 }) = 0 (0x0)

Shouldn't this be handled by fam/gamin in order to avoid this overhead?
While it does not produce notable load it prevents my processor from
saving power as well as spinning down the disks. I will gladly provide
more information on this if necessary.
