mount: could not find any free loop device

What can possibly use loop devices? There are eight processes called
loop0 through loop7, all started by kthread. But I've no idea what
they do and if it's them who are using the loop devices.

This is on Fedora 7.
losetup -a shows

/dev/loop0: [080c]:14073859 (/usr/local/kvm-images/WinXP.raw), offset 32256
/dev/loop1: [080c]:14073859 (/usr/local/kvm-images/WinXP.raw), offset 32256
/dev/loop2: [080c]:14073859 (/usr/local/kvm-images/WinXP.raw), offset 32256
/dev/loop3: [080c]:14073859 (/usr/local/kvm-images/WinXP.raw), offset 32256
/dev/loop4: [080c]:14073859 (/usr/local/kvm-images/WinXP.raw), offset 32256
/dev/loop5: [080c]:14073859 (/usr/local/kvm-images/WinXP.raw), offset 32256
/dev/loop6: [080c]:14073859 (/usr/local/kvm-images/WinXP.raw), offset 32256
/dev/loop7: [080c]:14073859 (/usr/local/kvm-images/WinXP.raw), offset 32256

and

losetup -d /dev/loop0

etc. gets rid of them, mount works again. What is still a mystery is
why all these loop devices were set up.
