Comment (by cypherpunks):
> I tested this code with IDEAL_SEND_BACKLOG for virtual (unlimit) low
latency local link (guest win7 to host linux), it goes to grow buffer to
2M without any reason, if to keep report ideal buffer (it says 64k)
without actual changes (system default sndbuf reported as 8k) then it
transfer with the same speed as with 2M buffer size.
Tested with latency 1, 5, 10, it wants 2M (probably depends maximum size
of system memory) always.
Outbound connection behaves differently, if some real latency present
(1ms, 10ms) it doesn't tries to get all available bw, IDEAL_SEND_BACKLOG
returns 64k every time.
