> With SLING-1725 the postservlet operations have been exposed as services to be consumed by other servlets.
> I use that to create two nodes with the ModifyOperation in one request. 
> However the second node creation might fail because of the postprocessors.
> In that case I want to return an error to the user and have nothing stored. 
> This can't be done at the moment as the AbstractPostOperation always saves independently from its context (so first node gets saved, second node not).
> I think it makes a lot of sense to let the caller of the operation have control over when the session is saved and introduced a flag to skip the save when requested.
> It is modeled after the isSkipCheckin flag.
