Per bug 1805427, comment 26 and bug 1807010, comment #2:

• rkv in SafeMode is not threadsafe (and making it threadsafe is a) hard, b) probably not worth it, and c) not likely the correct design to pursue)
• kvstore makes claims of supporting multiple dbs at the same path which have proven incorrect: bug 1805427, bug 1807010
  • The claims might've been correct under LMDB, but rkv is being used in SafeMode here.
• kvstore can resolve things refusing to open multiple handles to the same database.

This bug is about handling multiple consumers of storage at the same path. Be careful, have fun, and good luck.
