+ There can only be one writer for one database file. When you use dba on
+ a webserver and more than one request requires write operations they can
+ only be done one after another. Unfortuanetly some of the external
+ libraries simply fail or ignore this when trying to open the database for
+ another write operation. In this case you must use semaphores to guard
+ against. See <link linkend="ref.sysvsem">System V semaphore support</link>.
