> Socket code on windows allows multiple, simultaneous listening processes on broker port.
> C:\Windows\system32>netstat -anb
> TCP 0.0.0.0:5672 0.0.0.0:0 LISTENING
> [qpidd2.exe]
> TCP 0.0.0.0:5672 0.0.0.0:0 LISTENING
> [qpidd.exe]
> This is a security issue as it allows a rogue process to hijack connections directed to the broker.
> A simple first step is in Socket.cpp to change SO_REUSEADDR to SO_EXCLUSIVEADDRUSE as described in
