FYI: This patch seems to have broken all LLDB testing on Windows. I'll
investigate why.
Lots of the socket calls now result in stack traces like this:
Traceback (most recent call last):

line 78, in create_socket

ConnectionRefusedError: [WinError 10061] No connection could be made because
the target machine actively refused it
The changes to result_formatter.py are after the problematic line, so the root
cause it not immediately obvious. I have a guess that we're trying to open
more sockets than before and are therefore exceeding a handle limit imposed by
Python's use of ancient C RTL code.
