There's no reason for the C code to keep track of those things either.
So while the current implementation may happen to have the markers in
"creation order", it would be wrong to provide a primitive that promises
this ordering unless there's a *good* reason why we'd want to force
future Emacsen to also keep track of this info.  So far I don't see any
such reason.
