(TheDB_INCOMPLETE error will be returned if the buffer pool functionsare unable to flush all of the database's dirty blocks from the pool.This often happens if another thread is reading or writing the database'spages in the pool.)])m4_p([dnlIn the 3.X release, m4_ref(dbh_sync) and m4_ref(dbh_close) will returnDB_INCOMPLETE to the application. The best solution is to notcall m4_ref(dbh_sync) and specify the m4_ref(DB_NOSYNC) flag to them4_refT(dbh_close) when multiple threads are expected to be accessing thedatabase. Alternatively, the caller can ignore any error return ofDB_INCOMPLETE.])m4_page_footer
