winserver.py: A small script that runs a ZEO StorageServer and a ZEOTestServer.
    The ZEOTestServer is used to kill the StorageServer during a unit test's
    teardown phases.  As soon as a client connects to that server, it exits
    the process.

forker.py: Now forks and spawns, depending on os.
    XXX This needs to be cleaned up a lot, since the interfaces on Windows and
    Unix are nothing alike.

testZEO.py:  Add WindowsGenericTests and WindowsZEOFileStorageTests.
    These test cases use the Windows-specific forker interface.  They also
    use getStorageInfo() to describe the storage, rather than getStorage()
    to create the storage.  This is necessary because the storage instance
    is created in a separate process.
