I forgot to add that I need semaphores for INSERT and DELETE sql
statement for MySQL. Maybe this is not needed after all. The rows
that are concerned are using a column with an AUTO_INCREMENT
I don't need rollback (i.e. transaction). In its book on MySQL, Paul
Dubois write: "MySQL automatically performs locking for single SQL
statements to keep clients from interfering with each other." (Paul
Dubois, MySQL, New Riders, 2000).
