Win32::Pipe will let you establish a bidirectional named pipe. I guess the question becomes: can you establish a named pipe in server context with your win32 app? If so, then your win32 app sets up a pipe as a server, and your Perl script calls

if( $Pipe = new Win32::Pipe( $PipeName ) ) {
    # talk...
}
else {
    # continue polling. The client's call failed.
}

That way your win32 app is blocking, but your Perl app isn't.
