New Revision: 2656

Log:
avoid using a multicast IPv6 address for IOServiceTest.unavailableAddress
as NetBSD allows a TCP socket to be bound to it.  this behavior is
questionable, but even if it's an OS bug it's better to keep our tests as
portable as possible especially if it can be done by a trivial parameter
change.

fix is quite trivial, okayed in jabber, skipping formal review.
