 Is your program a PM application?
 No: You my do all your work on one thread.
    If you have to do some differnt actions at same time you can use
    one or more threads too.

 Yes: You *must* use an other thread for your file I/O because the PM messages 
must handled alway in 1/10s.

     Your PM thread is always waiting for messages. You can POST        to
them without having a own message queue by using        WinPostMsg(hwnd,
WM_USER + x, .....)
        The constant WM_USER is defined to give you a Chance to post    or
send user defined messages. So your PM thread can do    anything your I/O
thread is unable to do and the PM is not        knowing on except to present
you the message.

     You my syncronize your I/O thread with semaphores of any kind.     But
you should block your PM thred ONLY by Mutex semaphore  to block simoultanous
access to same memory locations or      other resources. DON'T block the PM
thread by Event semaphores!
