1) If you want persistent connections and fast aborts, open a second
   TCP connection. The beasts aren't terribly expensive.
   This is the approach suggested by DEC in their RFC1006+bells+whistles,
   draft-pouffary-tcp-01.txt

2) URGs are very badly supported in old BSD kernels.
   In fact, the interpretation of URG in 4.2bsd was incompatible with the
   specification, and had potential to cause screwups.
   (4.2bsd thought that the URG pointed to a byte of out-of-band data, which
   is not what the RFCs say; having several pending URGs could cause one
   of the bytes to be delivered inline)
   So, I would suggest *not* using URG for anything.
