Hi Ted,

  I believe the hook APIs were added in Equinox in Ganymede (3.4) - though 
someone can correct me if I am wrong.

  We certainly have not tested the dynamic weaving on a pre-Ganymede version. 
The best bet for users on earlier versions is to use static weaving.  Here is 
some info about our weaving support:

Are there cases where we could get into flush() with withinFlush set to true where we would still want writeChanges to execute?
