other until the window is closed. Then one of the sockets is closed, which
will generate a RST once the TCP at the other socket does a window probe.
All versions of FreeBSD prior to 11/26/2004 will ignore this RST into a 0
window, causing the connection (and application) to hang indefinitely.
On patched versions of FreeBSD (and other operating systems), the RST
will be accepted and the program will exit in a few seconds.
