I call it like this, the only event that is called is SslShutDownComplete which 
sets FSSLShutdownComplete property, I don't have any other event processing here


  EndTime := GetTickCount + FTimeout;
  while {$IFDEF USE_SSL} not FSSLShutdownComplete {$ELSE} False {$ENDIF} do
    if GetTickCount > EndTime then

I am now trying to use only main thread with socket, but there is another 
problem when I use it directly from main thread it works fine, but when I call 
it using Synchronize from another thread after first portion of data is sent 
socket closes with 10053 error. Any ideas what could be the problem? It is an 
SSL connection.
And how to recover from 10053 error? When I call Socket.Connect again it still 
remains closed.
