Mike Matrigali updated DERBY-4057:
----------------------------------
    Attachment: DERBY-4057_initial_prototype_patch.diff

Here is patch with initial prototype.  Still need to write new tests and pass existing.  Any comments on overall approach welcome.  Will be submitting another patch with more comments, tests, cleanup - so better to wait for that 
for detail review.

> If I repeatedly insert into a clob table and rollback the the transaction the space is not reclaimed and the number of allocated pages continues to grow.   I will add a test case to ClobReclamationTest and reference this bug.
> DERBY-4056 may be a special case of this bug, but I thought I would file a bug for the general issue.
