Two reasons:

* I don't think that it can be described as a best practice to begin 
with, and

* You could end up hiding what I would consider to be real problems in 
your code.

I want to detect real problems as soon as possible. Messaging 
deallocated objects, or objects that are in the process of being 
deallocated, is typically an error. The longer time you're unaware of 
something like this happening in your app, the more expensive it will 
be to fix it once it becomes a more serious problem.
