[Quickfix-users] SocketInitiator and SynchronizedApplication vs Application

[Mark T. K. <mke...@di...>]

if i'm using a SocketInitiator (connecting to a single party) with a
SynchronizedApplication instance, then it is clear that if a callback
blocks, it will block all other callbacks.

but if i'm using a SocketInitiator with a plain old Application
instance, what is the model?  if a callback blocks, will it block
any other callback?  e.g. is a single thread used to receive
messages and deliver the 'from' callbacks?
