Log:
  databases/cego: 2.26.7 -> 2.26.9
  
  - Version passed concurrent load test with 10 million concurrent
    operations ( random insert, update and delete on one table with 2
    processes )
  - Fix in CegoFileHandler::allocatePage, In case of page exceed with
    appendMode = true, a second try is done with appendMode = false
  - Small fix in CegoObjectManager::reorgObject, ref page id information
    for append mode is set to new last page id
  - Small fix in CegoSelect::filterRefs, allow expressions with constant
    values ( getAttrRefList= 0 ) in aggregation
  - Locking improvements for delete and update operations.
    All delete operations are done now via transactions ( introduced
    CegoTableManager::deleteDataTableAtomic ). This allows to use a
    shared lock as the table lock for using the table
    (CegoDistManager::deleteLocalDataTable and
    CegoDistManager::updateLocalDataTable )
    As a result, a table can be accessed in parallel during a ( long
    running ) delete operation on the table( e.g. delete from table).
    E.g. select count(*) from table will not block anymore, rather
    indicates the remaining number of tuples in the table.
    This modification is still under investigation and must verfied
    ( also in combination with btree/index objects on the table )
  - Fix in CegoBTreeManager::deleteBTree, the relevance value was not
    calculated correctly
    Fix in CegoQuery, cache invalidation is done before query operations.
    Otherwise, if the query is aborted, an exception is thrown and
    the cache is not cleaned
  - Small modifications on cgblow load simulation client
  - Changed locking for delete an update operations to exclusive due
    to concurrency prpblems with btree operations
  - Added page locking to AVLIndexManager and AVLIndexCursor
  - Improvements for locking done. Since locking is done on page level,
    Insert and delete operations can be done now in parallel . For this
    locking had to be introduced in CegoBtreeManager::insertBTree and
    CegoBTreeManager::deleteBTree
    Further performance path for grouping queries in CegoGroupSpace.
    Since the current grouping key is stored now in the class variable
    _groupSchema, some expensive list copy operations could be avoided.
    This improves performance for about 4%.
