Description:
------------
I want my persistent classes to have the same names as
the underlying tables, so I set 'class_prefix' to the
empty string. This works great...except that I happen
to have a table called 'Factory'. Calling
DB_DataObject::Factory() with an argument of 'Factory'
causes a segmentation fault. :-(

In the discussion for bug #3256, I see a
reference to this being a design decision. Fair enough;
but it's not made explicit in the documentation.

See bug #5484 for DB_DataObject.

Without having gone deep into debugging it, it's fairly
obvious how this might happen--it's no doubt a stack
overflow as 'Factory' gets evaluated repeatedly until
memory runs out. But, you needn't take my word for it--
just create a table called 'Factory', run createTables,
and try "DB_DataObject::Factory('Factory')."

I'd already turned overloading off, having been bitten
by PHP bug 25831 (which really ought to be pointed out
in the DB_DataObject docs).
