This change makes further effort towards improving our poll() implementation on the New Technology. The stdin worker didn't work out so well for Python so it's not being used for now. System call tracing with the --strace flag should now be less noisy now on Windows unless you modify the strace.internal.h defines to turn on some optional ones that are most useful for debugging the system call wrappers.
