- Win32: when using the threaded RTS, bypass the Async IO stuff and
just make blocking calls to read()/write().
This gives a significant performance boost to programs doing lots of
multithreaded I/O: in fact, a test program I have which does I/O
over 500 pipes simultaneously goes twice as fast with this change,
and is even faster than the non-threaded RTS (Windows only - Unix
changes are in the pipeline too).
- openFd: take an extra parameter to specify socketness of the file
descriptor rather than assuming that all streams are sockets. Some
streams (eg. pipes) aren't sockets.
