  Modified files:
    trunk/ChangeLog
    trunk/win32/win32.c

  Log:
    * win32/win32.c (NtInitialize, exit_handler): add initializing and
      cleanup of critical section object for select.
    
    * win32/win32.c (do_select): block reentrance.
    
    * win32/win32.c (rb_w32_select): 0 sec polling of socket. this is
      workaround because winsock cannot do select at same socket at the
      same time by two or more threads.
