My main use case is for insert_limit.
Tyr uses xarrays to keep track of resources allocated by userspace, and we need
to impose limits on how many resources can be allocated at once.
insert_limits() provides the exact semantics needed, i.e.: insert somewhere in
the array as long as there is vacant space in the given range.
