Since 1.10 `list_editable` on `ModelAdmin` is unusable for Models with a
large-ish dataset.
The problem is caused by a recent change to how the FormSet is generated
for the admin. Previously it was generated from the ChangeList result
list, but it has been changed to use the admin's `get_queryset` which will
return more than the current "pageful" of results (potentially the entire
dataset) causing Django to generate a form for each instance. This results
in Django consuming all available RAM and in some cases the python
instance crashing. My personal laptop became unresponsive and I had to
force power off.
