- * Locking/sorting note:

- * Sorting is done with the write lock, iteration and binary searching happens
- * under the read lock requiring being sorted. There is a race between sorting
- * releasing the write lock and acquiring the read lock for iteration/searching
- * where another thread could insert and break the sorting of the maps. In
- * practice inserting maps should be rare meaning that the race shouldn't lead
- * to live lock. Removal of maps doesn't break being sorted.
