I don't understand why you want to limit the rates just because
libcurl uses a WAN link. The link uses handshake (CRT/RTS) packets
to prevent heavy traffic to saturate the WAN link. What is 'Dtop'?

You could try setting the SO_RCVBUF+SO_SNDBUF options
on the socket(s). For example in SetupConnection() when
ConnectedPlease() == CURLE_OK.

See also Wget's limit_bandwidth() function.
