A soname change for a basic system library is a _major_ PITA and should be

I'd like to echo this. In my discussions shops doing large C++ development, they've made it clear that the disruption caused by a soname bump would be immense and should be avoided at all costs.

Jeff, please note that the path that Michael took from what was said ealier (in particular the quote he provided in his message) and the conclusion of "enthusiasm for soname bump" is still a mystery.
You'll note that I didn't include that portion of Michael's message.

My comments were meant to echo just the parts of Michael's message that I included inline. Namely that a soname bump is a huge problem and great lengths should be taken to avoid it.
