This makes sense at a first glance and according to the manual this setting
can be changed with ini_set().

But I bet it won't work, because the whole deal of this setting is, that the
session is started during the request startup *before* the page loads. For
this reason, you can't store objects in the session if you use this
feature. Changing this setting during the page execution shouldn't change
anything, or did you make other experiences?
