The conversion from CIRCLEQ to TAILQ is broken, the semantics
are not really the same. But the real problem is that the code
also abused the CIRCLEQ structure by using a NULL cqe_next
pointer to signal that a node is not queued.
You could create a new hack that works with TAILQ (you need
tqe_prev because tqe_next can be NULL for queued nodes), but
I propose to remove such abuse completely at the cost of a
slightly larger mem_node structure.
Please have a look at
With this Xamiga doesn't cause a panic anymore.
N.B. the Atari port uses almost identical code to manage "st memory".
Whatever we chose as a solution could be applied there too.
