Since 2010-09-28, the implementation of TIP #162, "IPv6 Sockets for Tcl", I have the
following problem on Windows (only tested on Win7, but I suspect XP and Vista as well)
The two mentioned test hang about 50% of the times. Before 2010-09-28 I
never saw that happen. I used mingw-compiled head, but I supect that with
VC++ 6.0 the same happens, because the socket implementation in both
is based on the winsock2 dll.
When commenting out those two tests, all other tests run fine.
Andrea, did you notice it as well?
I didn't investigate yet where exactly it hangs, but as soon as I have
more information I will add it here.

Re-assigning to Reinhard as the IPv6 go-to guy.
When jdc just tried it with vc9, the server process of io-53.10 even creashed leaving the following message in its stderr file:
--- snip ---
2COPY
...
alloc: invalid block: 01CE5490: ef ef 0
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

Looks like we need somebody with good Windows debugging skills...
Fixed already in 8.6.0
