CSP "encapsulated" in UML?

[Roy Wilson <designrw@xxxxxxxxxxxxxxxx>]

Gerald,

I've got some demo JCSP code that I want (eventually) to diagram in UML, 
so I'll be eager to see what you have/will come up with.

More generally, using UML might be another way of subverting "pure" 
OO-thinking: CSP as a kind of mind-virus (or meme?) transmitted via UML. 
Or not :).
