You know, I just installed MTR, and the connection is pretty good.
Average latency of 65ms on all hops in the route, and only 1 or 2 hops
drop like 1% of the packets.

But I did some system call traces (strace) and it seems that somehow the
connection gets stalled (some read() calles take like tens of seconds to
return 1024 bytes of data!!).  Something is up with my NNTP provider.  I
am going to resolve this issue with them... perhaps they are overloaded
during the day or something.

But it's nice to know Pan isn't to blame, and that it tries its best to
avoid dead time by being threaded well!

Now to figure out what to do about my news server... :)
