Since there is nothing GTK/WPE-specific here, I think I would move this to a WebProcessProxyUnix.cpp and guard it with #if !PLATFORM(COCOA). Then instead of #if PLATFORM(MAC) || PLATFORM(GTK) || PLATFORM(WPE) guards, you would only need to use #if PLATFORM(MAC) || OS(UNIX) guards instead.

Um, is OS(UNIX) true for PLATFORM(IOS_FAMILY)? I'm not sure. Got to be careful about that, if so.
