By default, TTree::Draw process 10^6 events.
This default value can be changed by TTree::SetMaxEventLoop.
As we see many Root users processing a very large number of events,
we have changed the default for the coming version to 10^9

The profile problem you reported is also fixed. An updated
version will be put on the Web. We will announce the few changes
once it is ready (very likely tomorrow Thursday).
