After thinking a while about it, it is no longer clear to me, why there is a 
need for chunked output *at all* ...

The reading side of a pipe can always read the data in arbitrarily (and 
independently of the sender) sized packets, even when using synchronous I/O, 
by simply specifying the size in the read() call. The sender must of course 
check how many bytes of it's write() call actually got written.
