I don't know about CGL, but a unified async notification mechanism _is_ needed. In ~2002, I needed one, and what I ended up with was a Red Hat 2.4 kernel with IO_CMD_POLL hacked in. Five years later, mainline still can't do that.
Whether it's syslets, threadlets, io_getevents with networking support, kevents, epoll with kaio support, queued signals, or something else, users don't care, but they need _something_. Please don't ignore the users just because they quote the wrong text. The need is very real.
-- Do not meddle in the internals of kernels, for they are subtle and quick to panic.
