Comment(by mstone):

 For what it's worth, as a userspace developer, I often care about writing
 programs which make delicate changes atomically with respect to other
 userspace processes in order to avoid racing with those processes
 according the vagaries of the scheduler. In general, my ability to
 accomplish this has strong implications for the security, correctness, and
 failure-tolerance of my software. (Look at all the pain surrounding
 creation of tmp-files, the introduction of the f* file manipulation
 variants, or the ppoll() and pselect() extensions for easy examples.)
 Consequently, and speaking generally, I would be happiest if an underlying
 atomic interface were provided when possible and if a "high-level shell"
 interface were made available separately. Any reason it's inappropriate
 for the kernel to provide both? (Or to build the high-level one in
 userspace atop the atomic kernel one?)
