This is a large push. Included are :

Browse Source 
* multi-table updates
* new paid feature for limiting number of queries per hour for users
* optional syntax for multi-table deletes
* optimization for SQL_CALC_FOUND_ROWS
* a small addition for CREATE .. SELECT that will be of future use

I know that all this will require many additions to documentation, 
which I have not done, but I am at Arjen's disposal to help him document
all this.



libmysqld/lib_sql.cc:
  This is a small change required due to new paid feature of limiting 
  number of queries per hour for each user.

BitKeeper/etc/ignore:
  Added 50 sql/new.cc to the ignore list
scripts/mysql_install_db.sh:
  This is a small change required due to new paid feature of limiting 
  number of queries per hour for each user.
sql/item_timefunc.h:
  This is a small feature that will be of use later in the proper 
  creation of the tables out of CREATE ... SELECT...
  
  Further changes will come after this resolve/push/test passes ..

  queries per hour (paid feature).
sql/sql_parse.cc:
  Ha ! So many changes. 
  
  * multi-table updates
  * limiting number of queries per hour for users
sql/sql_select.cc:
  Optimisation for SQL_CALC_FOUND_ROWS, when a query involves a single
  table, without WHERE or GROUP clause

  multi-table updates
sql/sql_yacc.yy:
  Many things :
  * multi-table updates
  * limiting number of queries per hour for users
  * new optional syntax for multi-table deletes. This one is different 
    from the one demanded by user. USING clause MUST include ALL tables, 
    not just the ones that are used and not deleted from.
