cubicweb #3369614 SqlGenobjectstore and rql.execute [rejected]

Executing store.rql('UPDATE...') yielding to session.rql('UPDATE..') and store.relate(...) with an inlined relation (thus yielding to an SQL update statement), leads to a postgres deadlock. This should be fixed or at least documented as a limitation.
