First I'd like to comment that I like Roy's updates to this page.

No.  Well, true for non-persistent PUTs. 

Remember that the server can close the connection at any time, either due
to a timeout, load, the current revision of Linux... whatever it feels
like.  After the server closes the connection, data from subsequent
requests will send a RST to the client without lingering_close which is
bad.  This should, in theory, happen less now that the default limit is
above 5 requests per connection. 

PUTs and pipelining (actually it isn't just pipelining but potentially any
persistent connection) can break.  I don't think it is happening much with
today's clients, but I don't think most (any?) of them implement
pipelining.

Come again?  Sorry, I'm not sure I'm parsing that the way you intend.

No more than me...
