This adds a counter and a 'dead' flag to the data stored in the linked list. The counter counts the number of iterators (still) pointing to an element and the dead flag is set to indicate the element was erased when iterators are still pointing to it. As a result, iterators are NEVER invalidated. Of course, such elements are subsequentially skipped when iterating over the list. Assertions protect against dereferencing an erased iterator, but incrementing or decremention still works: it is still well-defined what the next (non erased) element is, assuming the element wasn't erased (yet), but would be erased delayed - or assuming the iterator would have been incremented (decremented) in advance to erasing the element.

Sin-gu-la-ri-ty (noun) - a distinctive feature, a uniqueness; a point at which
continuity breaks up; a point in history at which machine becomes smarter than
humanity and/or fuses with it indivisively; or simply a cool sounding word with
the initials S.G. in it :)
Singularity Viewer is a SecondLife(tm) protocol compatible client application.
It can be used to access SecondLife services as well as a number of others such
as those based upon the OpenSim platform.
Singulariy is maintained by a small group of volunteers who can be contacted
both, in-world (SingularityViewer group) as well on IRC (#SingularityViewer
@ FreeNode). Bug requests and features requests can be submitted through our
Issue Tracker (http://code.google.com/p/singularity-viewer/issues/list or from
the viewer menu: Help --> Bug Reporting --> Singularity Issue Tracker...)

History
The Singularity viewer was started by Siana Gearz in November 2010 by forking it
from the Ascent Viewer, by Balseraph Software Group, which in turn was based upon
source code modified from the snowglobe source code released by Linden Lab.
