I do agree that the hlist versions aren't very nice in this regard. The 
regular lists are much better at moving lists around.

Agreed. It would be better if the people who use hlists most (I think that 
would be networking) would think about this.

Silly boy. Next you'll ask me to _test_ any patches I send out.

Anyway, I think your patch is likely fine, I just thought it looked a bit 
odd to have a loop to move a list from one head pointer to another.

But regardless, it would need some testing. Daniel?
