Cool - any chance you can tell us what the app is? :)

This one I have a gut reaction against, though I certainly see your  
use case. I'm not sure how widespread that need is, though, and I feel  
like having more fine-grained control over which methods are exposed,  
for all backends, would be better. Unlikely that can be done without  
breaking BC though, so I'm neutral on this for now.

This seems fine to me.

I'd make the level PEAR_LOG_DEBUG, but otherwise this is good.
