All, I'm doing some background literature review relating to microkernel designs and highly-concurrent programming models. The KSE API was one of the primary examples of an activation-style threading API, before it was ultimately abandoned due to the problems that arose. I'm interested in tracking down sources, like reports, discussions, or possibly testimonies from people who were involved that talk specifically about the nature of those problems. I'm aware of the overall design and the sources describing it; the sense I got from some old email threads of the problems it that they were mostly related to mismatches between the programming models that would benefit most from that style of activation and the POSIX thread/signal semantics. If anyone is aware of sources that go into greater detail and could point me to them, it would help me out a great deal.
