stdio FD >= 3

[mmastrac]

One current shortcoming of the Java process API is that it doesn't support communication on FDs >= 3. This is easy to do on *nix OSes, but requires a bit of trickery using the lpReserved2 field in STARTUPINFO to work in Windows:

This can only ever work for Windows CRT-based programs, but I think it is "better than nothing".
