#69 Gigantic node lister can get lost

[Jay Bonci]

In gigantic node lister, it can get lost if you follow
a few certain steps:

*) Go a few hundred nodes into your system
*) Change to a type where there aren't a few
hundred nodes (such as a superdoc)

This leads to some broken functionality for which
you have to leave and return to the doc to get it to
work right after that.
