#8937: boost::asio::ip::tcp 5000ms stall

 Under certain circumstances, the boost::asio::ip::tcp module exhibits a,
 with a bit of patience, reproducible behavior of every now and then
 stalling for quite exactly 5000ms.

 On May 02, 2011, a discussion about this was started by Torben Wiggerich
 on the Boost Mailing List:

 On May 09, 2011, a traffic dump was requested by Cliff Green.

 I ran into the problem some time later and posted a traffic dump on Apr
 02, 2012. No one has replied since.

 Today, I tested whether the issue still persists with

 Boost 1.49.0
 Boost 1.53.0
 Boost 1.54.0

 and it still occurs with all of them.

 For the CPU I used an Intel Core2 Duo P7350 @ 2.0 GHz, because this bug is
 only reproducible in a reasonable time frame (under 1 hour) on a
 sufficiently slow computer. Back then I used an Athlon X2 4400+. An i7
 will be too fast to show this behavior reliably, or in a reasonable amount
 of time, or maybe even ever.

 The operating system used was Windows 7 x64 SP1.

 The compiler used was Visual Studio 2008 SP1 x86 + all updates from
 Windows Update.

 I attached a Repro Case based on the code posted by Torben in the Thread.
 With this, on the Core2Duo I used, the behavior was repeatedly observable
 in under an hour of Server + Client running.
