19340	django.forms.Field is not thread-safe	anonymous	nobody	"django.forms.Field has the 'creation_counter' attribute which is incremented when an instance of django.forms.Field (or one of its subclasses) is created. I DO understand that it's a bit unusual to create
forms in the runtime, so this must not be a big issue (or not a bug at all), but it should be documented somewhere.
