I thought reading the section would be enough. Sorry. Too much
multiplexing.
1) you have to look at the codes to know whether what you
observed is a bug.
2) ignoring ICMP *except* during initial tcp negotiation seems
suboptimal -- the destination can disappear completely at
any time. May be this results in an extra delay before a
connection is declared dead. But I no longer remember
many details of tcp to know if this matters.
3) my main point was to check the rfcs to resolve such issues
