The output is puzzling. It shows syncprov_db_close accessing a persistent
search structure that was already freed in syncprov_op_abandon. The puzzling
part is that syncprov_db_close can only find ops by following the si->si_op
list, and syncprov_op_abandon always removes ops from the si_op list before it
frees anything.
Will have to look into this later, but now you can see why this feature is not
part of the public 2.4 releases. Nor will it be, it's a 2.5 feature.
