You have to do inter-process synchronization, pipe handles can be
shared between processes. I don't see how you can do that without
putting everything into the wine server, which is the same as putting
it into the kernel except with a large performance hit (and not only
for named pipes, but for all file I/O, since it will prevent many
optimizations). But feel free to prove me wrong; I haven't studied the
protocol in detail so maybe I'm missing something.
