This patch doesn't remove the message, it just removes the 'could not reserve' messages,
which would be useful if they are actual errors, but they are not. It's pretty silly if
the left hand doesn't know what the right is doing... However in the interest of keeping
the code as is, I guess the patch isn't all that important.

David.
