Writes to disk files don't suffer EINTR as far as I've ever heard
(if they do, there are an awful lot of broken programs out there).
More to the point, a kernel that aborted a write because of an interrupt
*and failed to set errno* would certainly be broken. The question is
what to assume when we see that the write did not change errno.
