-# When a new database is attached, the connection doing the attaching 
-# tries to load any unloaded schemas for both the new database and any
-# already attached databases (including the main database). If it is
-# unable to load any such schemas, then the ATTACH statement fails.
-#
-# This block tests that if the loading of schemas as a result of an
-# ATTACH fails due to locks on the schema table held by other shared-cache
-# connections the extended error code is SQLITE_LOCKED_SHAREDCACHE and
-# it is possible to use the unlock-notify mechanism to determine when
-# the ATTACH might succeed.
-#
-# This test does not work for test-permutations that specify SQL to
-# be executed as part of the [sqlite3] command that opens the database.
-# Executing such SQL causes SQLite to load the database schema into memory 
-# earlier than expected, causing test cases to fail.
