Again not necessarily, I trigger activities off a timer and messages, 
and so a sync FTP download does not stop the time running other things 
at the same time, provided any 'waits' are calling ProcessMessages to 
keep things moving (and there are no sleeps).  I only use threads for 
pings, since they are blocking.  One application is doing once a second 
async comms at the same time as sync FTP downloads.  

I don't disagree that use of async events is better, particularly for 
servers, and I use them for simple socket applications that don't have 
complex states.
