           Summary: Windows client disconnect behavior

Summary: When testing gst-rtsp-server using the test-launch example, I am
seeing odd behavior with how the server handles disconnects on Windows.

Test Setup: 
 - Using test-launch example on Windows with pipeline : videotestsrc ! jpegenc
! rtpjpegpay
 - Connect multiple clients to the server using a script running multiple
instances of playbin. (Seems to happen reliably with more than 10 streams)
 - Close all playbin instances.

Observed behaviour:
 - With the server running on Linux, all of the sessions within the server were
immediately detected as closed by the RTSPWatch and the closed() function of
rtsp-client was triggered. The sessions are closed quickly.
 - With the server running on Windows, some sessions disconnected in the same
manner as the Linux server (fast), however others catch errors from udpsrc
indicating a flow error:
rtspmedia rtsp-media.c:1788:default_handle_message: got error Could not read
from resource. (gstudpsrc.c(573): gst_udpsrc_create ():
/GstPipeline:media-pipeline/GstUDPSrc:udpsrc20: receive error -1: Error
receiving message: An existing connection was forcibly closed by the remote
host.)
rtspmedia rtsp-media.c:1487:gst_rtsp_media_set_status: setting new status to 5

It appears the RTSPWatch is not always detecting the closure of a connection on
Windows. The abnormal disconnection process seems to take longer and blocks any
incoming connection requests making the rtsp server unresponsive.
