I do agree that Windows is garbage, but if you consider QEMU an
entry-level tool to ease migration to more robust platforms, then it
becomes interesting to actively support 'Doze.

Posix is supported as a subsystem in 2k, but in XP M$ stripped it out.
One would have to download the Interix subsystem (SFU), which is
farily large. Hardly an option to push onto users if forking is much

Yes, there is, from native win32 *code*. Not by userland tools (which
kills the 'mkfifo' approach). At least I haven't stumbled upon one
that does exactly this. 3rd party included.
