another way to read from WinBoard is to use a separate thread blocked on
ReadFile().  it's more complex because you also have to arrange for safe
shared data between the search and reader threads.  but for me the net
effort of threads was less, since the structure of my internal interfaces
meant that i could port to win32 by replacing SIGIO and SIGALRM
handlers with threads in an encapsulated way.
