1. nothing almost working will be applied, it has to be fully working
2. fix your mailer, most people hate having to search for mails with
   similar subjects to find the patch you are talking about
3. ive said many times that replacing balign <-> p2align will not happen
   this must be done with a macro and that macro must not be in a x86
   specific file
4. indepenant changes must be in seperate patches (the align change is 
   such a thing)

no mac-intel patches passed these trivial criteria IIRC

In the past you could go to a library and read, borrow or copy any book
Today you'd get arrested for mere telling someone where the library is
