QSslSocket emits readyRead while in write()

Message 1 in thread

I have a problem with QSslSocket. If data arrives at a socket during a 
write() call, the socket will emit readyRead(). This causes reentrancy 
problems for me.

For example, what if the message received is "I want to disconnect"? 
Then the socket is closed and deleted by my program, meaning by the time 
the write() call returns it's dealing with a deleted socket.

I may be mistaken, but I believe that QTcpSocket "held on to" the 
readyRead() until it was back in the main event loop. Does anyone know 
of a way to make QSslSocket do just that?

Can you test Qt 4.4? I've changed the behaviour of QSslSocket and it should no 
longer cause you the reentrancy problems.
