The default should max out at 25 per bus.   Basically, they end up on the 
"default" WorkQueue of the bus which default to a max of 25 threads.   You 
can configure the default WorkQueue to have more or less threads if you 

There is supposed to be code to allow for a specific "http-conduit" named 
workqueue to be optionally configured, but I just noticed that code isn't 
working properly and will always re-grab the default workqueue.  I'll get 
that fixed.

You can also call the Service.setExecutor(..) prior to creating the proxy if 
you want to specify a specify executor for the client.
