+Oh, finally, a performance issue (that probably doesn't matter for
+lmtp2nntp):
+sa_rc_t sa_read(sa_t *sa, char *cpBuf, size_t nBufReq, size_t *nBufRes)
+always flushes the write portion of the outgoing stream, even if the
+read is going to be entirely from the local buffer.  This is generally
+undesirably behavior, since you can trigger nagle's algorithm if
+you're a command/response server with pipelining like LMTP.
+Generally, you want to flush the write portion whenever you're about
+to block on a read, but not necessarily before.
+(Of course, the client-side of a pipelining client is considerably
+more complex.)

 - on resolving multiple addresses can be returned (especially
   one IPv4 and one IPv6!) and each one has to be tried on
   socket+connect for instance. What to do? See also
