I think we have control over that. According to
https://msdn.microsoft.com/en-us/library/windows/desktop/ms724466(v=vs.85).aspx
CreateProcess() has to be called with bInheritHandles = true (which we
do for backends), and SECURITY_ATTRIBUTES.bInheritHandle has to be true
too.  The latter we already only do for InitSharedLatch(), but not for
InitLatch(), nor for the WSACreateEvent's created for sockets - those
apparently can never be inherited.

So that kind of sounds like it should be doable.
