-/* Test forking while holding lock.
- *
- * There are only five ways to do this currently:
- * (1) grab a tdb_chainlock, then fork.
- * (2) grab a tdb_lockall, then fork.
- * (3) grab a tdb_lockall_read, then fork.
- * (4) start a transaction, then fork.
- * (5) fork from inside a tdb_parse() callback.
- *
- * Note that we don't hold a lock across tdb_traverse callbacks, so
- * that doesn't matter.
