Well i did some testing this morning as my VPN connection was borked all weekend.

__xen-unstable does not leave any tapdisk processes running.__

In fact it would seem that tapdisk is only started to spawn the block device and then ends.

I may be misreading normal behavior here: However the udevd processes that are started when a guest is created will stick around even if the guest is shut down but will be replaced with different udevd processes for the next created guest.

Nevertheless i applied you patch an tried again.

That gc &gc fix wasnt neccessary to patch.

The patch had no visible effect.

I hope this info helps in creating a patch for 4.1
