Must specify protocol for client-uvm sharing of signal handlers
Created by: mn200
As per discussion in meeting on 1 August 2014, we think that the uVM should be the only entity making the
signal system call. Other entities (i.e., clients in practice) can register signal-handler-like objects with the uVM, which promises to pass on signals generated by their code.
This needs to be documented in the spec-wiki, perhaps in a section about client-uVM API.
