restore(8) && used memory not freed-up

[Matthias Apitz]

Hello,

I was restoring some files which I removed while updating from KDE3 to
KDE4 and encountered the following interesting problem:

# mount -o ro /dev/da1s1a /mnt
# cd /tmp
# restore -x -f /mnt/Tiny/dumpsTiny-20131025/usrLocal.dmp ./guru/.kde/share/apps/knode

after the restore was finished(!) the memory in top was shown as:

Mem: 535M Active, 1136M Inact, 270M Wired, 28M Cache, 90M Buf, 14M Free

only the unmount of the device freed-up the memory:

# umount /mnt

Mem: 535M Active, 46M Inact, 192M Wired, 8104K Cache, 90M Buf, 1203M Free

Why is the memory reserved by the system (10-CURRENT, i386)?
Thanks

	matthias
