/**
* Use this method to activate data tainting for this object
*
* Data tainting enables a check to the database every time a value is read from
* this object. This can mean quite a lot of extra database activity, however it
* is useful if you are concerned that there maybe a situation where a process is
* might load some data from the database, and in the meantime another process might
* write to it and this would potentially cause problems if the data that was already
* in program memory weren't updated.
*
* Once an object is tainted using this method, you should put a try/catch block
* around every call to a {@link read()} related method (such as set, get, fetch)
* to catch a {@link TaintException} that may be thrown and deal with it.
*
* @access public
* @see set,get,fetch,read,save,delete,TaintException
