I agree.  As a matter of fact, I think we should consider adding a  
statement in the coding guidelines document that says to always use  
calloc, unless un-initialized memory is acceptable.  Furthermore, we  
should require that a call to malloc without a corresponding memset  
have a comment noting why this is the case.

I was planning on going through and cleaning most of this up once the  
patch discussed in bug 4996 got accepted.
