[webkit-dev] Ref counting questions

[Bem Jones-Bey]

Hey all,

I've read the document at http://www.webkit.org/coding/RefPtr.html, but I still have some questions about using RefPtrs.

The first one is listed in the "Improving this document" section of the aforementioned documentation:
	• Perils of programming with TreeShared.
What does that mean? What gotchas should I be aware of? (Heck, more details on any of the things in "improving this document" would be helpful, and I'll do my best to update the document with anything I learn if that's desired.)

Also, I've noticed that there's both TreeShared and RefCounted, and they seem fairly similar to my uninitiated eye. What's the difference between the two and when should one use one or the other? Also, are there other templates/classes that I should be aware of?

Thanks,
Bem
