+In other cases, the libc function may send fewer bytes than
+@var{count}---for 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.
