    Hi Thierry,

    
    we already had started to discuss on IRC, but here are my thoughts
    again.

    
    Is it necessary to explicitely set the txn in the plugin ? The txn
    will be found when ldbm_back_delete() does dblayer_txn_begin(9 and
    it checks the per thread stack of txns. 

    In my opinion the real problem is not to set  the txn in id2entry,
    which will then try to read a locked page.

    
    Ludwig
