Actually, using the wording `enforce data integrity completition' was
bogus.  What I really meant to express was `synchronize file data'
instead of the former.  This primitive isn't meant to make guarantees
about the completition of I/O unless synchronous operation has been
requested explicitly.  So, no, the situation you've outlined will
*not* cause synchronous operation.
