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?)
