v2 LGTM, with two small nits:
1. Grammar feels shaky here:
+ * normal case where we're asked to recurse, this routine ensures that the
+ * not-null constraints either exist already, or queues a requirement for them
+ * to be created by phase 2.
The "either" seems to apply to "ensures" versus "queues", but it's in
the wrong place for that. Maybe something like
+ * normal case where we're asked to recurse, this routine checks if the
+ * not-null constraints exist already, and if not queues a requirement for
+ * them to be created by phase 2.
2. Stupider compilers are likely to whine about the "children"
variable possibly being used uninitialized. Suggest initializing
it to NIL.
