Btw.: I'm not sure write(),writev() and pwrite() are allowed to do short writes on regular files... ?
I believe it is the intent of the Standard to prohibit this (a paragraph in the rationale says that short writes can only happen if O_NONBLOCK is set, but this is clearly wrong because the normative text says end-of-medium also results in a short write) but there does not appear to be any language which requires atomic behavior for descriptors other than pipes and FIFOs.
As a quality-of-implementation matter, for writes to regular files not to be atomic would be considered surprising.
