'Drug cocktail' to fix /tmp bugs

@epa:
Actually, fixing all of Debian (I take that as a synonym for "fixing all the software you can find") still does make sense even if the Linux kernel "fixes" this issue: There are still heaps of other Unix systems that might be affected by the same insecure temporary file handling problem, there are lots of systems running older kernels but sometimes (manually compiled) newer applications,....
So in either case, I think the kernel should take measures appropriate to mitigate this attack vector, while applications should be fixed to use more secure access patterns to avoid this problem (both on Linux and on other potentially affected systems).
