Release 4.1: DB_ENV->memp_sync

Historical documentation for the DB_ENV->memp_sync method stated:

In addition, if DB_ENV->memp_sync returns success, the value of
lsn will be overwritten with the largest log sequence number
from any page that was written by DB_ENV->memp_sync to satisfy this
request.

This functionality was never correctly implemented, and has been removed in the Berkeley DB 4.1 release. It is very unlikely application programs used this information. If your application used this information, please contact us for help in upgrading.
