   +In other cases, the libc function may send fewer bytes than
   address@hidden instance because @var{out} is a slow or limited
   +device, such as a pipe.  When that happens, Guile's @code{sendfile}
   +automatically retries until exactly @var{count} bytes were sent or an
   +error occurs.

A short write is an opportunity for the caller to Do Something Else
(i.e., go asynchronous).  I think that is more useful than internalizing
the looping.  To accomodate both usage patterns, you could leave the
low-level proc as-is (as-was :-D) and provide another proc that loops.
