This is to ensure that all MPI routines are called before MPI_Finalise is called. Resolves: gh#3041
The list from gc was incomplete. Using a custom weakref list ensures we can free all objects before MPI_Finalize is called. This reverts 0e4314c, which was not working as it relied on the same, incomplete, list of objects. Resolves: gh#3041

Another option that might be easier to read would be to just template this function

So you mean move this to a separate file?
I do not think it would get much easier.
Certainly the file is a bit long and hard to read, but I am not sure moving this macro to a different file helps a lot with cleaning up.

Sorry, I meant just have something like:
{% macro class_cinit(init_args="*args, **kwargs", defaultSO=True) %}
cdef c.bool isSelfOwned
cdef object __weakref__
def __cinit__(self, {{ init_args }}):
...
{% endmacro %}and use like:
cdef class Mesh:
...
{{ class_cinit | indent }}Avoids inheritance, reduces the duplication from the __cinit__ method, and keeps the class definitions looking normal
