synchronous sockets, block

I _really_ need to implement synchronous (i.e. blocking) sockets.  QSocket is 
a great class and I appreciate that it is asynchronous but I don't _want_ 
asych sockets.  Just trust me on this.

So I tried implementing a solution involving QWaitCondition variables but it 
seems to me that when placing a single-threaded app like mine to sleep using 
a QWaitCondition, the QSocket will never speak up and send its signal.

What options do I have?  Has anyone implemented synchronous sockets?  Has 
anyone got any other suggestions?  I'd rather not move all of my socket stuff 
to a separate thread... if I'm going to do that, I'll write my own socket 
code that is synchronous, does not rely on Qt, and works in Windows and Linux.

Sorry, I can't trust you just yet.  Can you elaborate as to why you need 
blocking sockets so bad?
