           Summary: Socket.Available == 1 when socket.Receive return 0
    Classification: Mono

When a socket tcp connection is closed the socket.Receive return 0 bytes but
socket.Available still return 1.

Either socket.Available should return 0 since there is no more data to be read,
or socket.Receive misses the last byte.

This occurs in a http proxy but only a few times a day.



Reproducible: Sometimes

Steps to Reproduce:
1. Run HitProxy

2. When the process start to consume 100% cpu, the loop running gets stuck
since socket.Available == 1



I have received solution to my original problem elsewhere.
This bug is only about the socket.Available property.
