Umm, no, Luc. "Object is in use" means that a DDL request cannot be satisfied "for some reason related to the keys". So, not having the script running with exclusive access will throw this exception....but so will attempting to reference a foreign key constraint to an uncommitted PK or unique constraint key. The latter has never been possible in IB or FB and it still isn't.

Somehow, I think your "luck" over the years must be related to using an autocommit transaction for your scripts...but using "client-side autocommit" (AutoCommit true) isn't recommended for DDL, anyway.
