On Windows, perl no longer calls CloseHandle() on a socket handle. This makes
debugging easier on Windows by removing certain irrelevant bad handle
-exceptions. It also fixes a race condition and possible test failure in
+exceptions. It also fixes a race condition that made socket functions randomly
+fail in a Perl process with multiple OS threads, and possible test failures in
F<dist/IO/t/cachepropagate-tcp.t>. [perl #120091/118059]
