Hi Bruno,

FYI, I've just checked in this change to restore
the old (coreutils) behavior:

        * safe-read.c (EINTR): Define.
        (safe_read): Rewrite to iterate IFF the read fails with EINTR.

because the previous version didn't work as used by cat.
The particular test case is a bit obscure:

  Type `cat', then give it a few bytes of input and type ^D.
  Normally, that is enough to make cat terminate, but with
  the previous version it wasn't; I had to type ^D again.
