Optimized CLEANUP_ORPHANS query for H2 1.4.x

Browse Source 
Original query from dbStatements.properties writes millions of records from subselect to file system due to MAX_MEMORY_ROWS Setting http://www.h2database.com/html/grammar.html?highlight=max_memory_rows&search=MAX_MEM#set_max_memory_rows
Database maintenance task therefore takes forever.
The new query (copied from postgresql) works way faster.
