Copying a struct is fragile, Mike Roth pointed out the potential issue
with aligned_buf.
If raw-posix could open from a given file descriptor as an alternative
to opening a filename, then it would be clean and natural to simply
re-initialize from the dup'd file descriptor in the abort case. That's
the approach I would try instead of stashing the whole struct.
