Is really an appropriate analogy? Using fopen or open is an implementation detail whereas the choice of thread implementation is a pretty fundamental design decision. I agree there are similarities. Both filesystem I/O and threading do require some degree of awareness of the operating environment, but I'd argue that dependency is stronger with threading. From a pthreads user's perspective the proposed API is close enough to pthreads with default options it be usable. Provided implementations provide a means of mixing native and C1x thread, there shouldn't be many barriers to their adoption. For example, on Solaris older native threads are compatible with pthreads, so the two can be mixed in the same application. -- Ian Collins
