Eliot Miranda uploaded a new version of NetworkTests to project The Trunk:
http://source.squeak.org/trunk/NetworkTests-eem.41.mcz

==================== Summary ====================

Name: NetworkTests-eem.41
Author: eem
Time: 28 March 2016, 3:28:59.175834 pm
UUID: edf75dc3-4a00-4751-9db5-427ba6e5687a
Ancestors: NetworkTests-ul.40

Improve testSocketReuse.  It seems correct that the SocketPlugin answers whatever bit things like  SO_REUSEADDR set in underlying socket fields, not the 1 that the test expects.  e.g. on Mac OS X 
	Socket newUDP
		setOption: 'SO_REUSEADDR' value: 1;
		getOption: 'SO_REUSEADDR'
answers #(0 4), not #(0 1)
