Does the reason for that still exist? At this point we have refactored 
all the cross-platform code so it no longer (I don't think) mixes tcp 
sockets with other types of unix fds; the critical codepaths are 
sockets-only and the other types of fds would be unix-only. We also 
introduced DBusPipe to hold pipes.

The DBusSocket struct in sysdeps-win.h still has comments about 
emulating unix domain sockets but that should no longer be necessary 
since we moved the unix domain socket code to unix-only files.

One of the older ideas was to create a stream/file/socket abstraction, 
but what we ended up doing instead was to avoid unifying those and just 
have separate sysdeps.h APIs for each type of thing (files, pipes, sockets)
