I would say that it's unsupported, and surprising that it actually worked
for you. It would require some non-trivial engineering to get it fully
working on Windows. For example, to access data via HTTP, one would need to
implement or integrate an HTTP client based on Windows sockets, as well as
abstract Jim Kent's code, which is based on POSIX-specific things like
integer file descriptors.
