It always opens the file in O_RDWR mode, so callers have to do extra
syscalls if they want to make the file write-only, etc.

Also, in cases where the temporary file will be moved to become a
non-temporary file, it is good to create the file on the same file
system as the final file so that it can be moved atomically.  There
is no support for locating a temporary directory on a specified
file system.
