Comment(by simonmar):

 Note that compiling ''different code'' and hoping to get the same ABI hash
 is a much more difficult proposition than getting the same ABI hash by
 repeatedly compiling the same code (which is what this ticket was
 originally about).  I realise it's a reasonable thing to want to do, but I
 just wanted to point out the distinction.  We need to solve the easier
 problem first before we can tackle the harder one.
