    As they are currently implemented, the markers use the sorted module
    list for marker listing, but I can change their implementation so they
    do not require this (and make it a subsequent patch instead).

    I could do that to diminish the patchset size a little more. However, it
    implies using an interface with a known race condition. Could we just
    post this as two different patchsets instead ? I really think the sorted
    module list would be important to get in and I don't like to use buggy
    unfixed lower level functions.
