Project Loom: Fibers and Continuations for the Java Virtual Machine

I wrote the proposal, and I did not mention this paper because that would be going into too much detail. However:

1. The paper discusses an implementation of lightweight threads in cooperation with the kernel, in a way that requires switching back and forth between user and kernel mode.

2. The paper was written before the advent of work-stealing schedulers (first popularized in Cilk). Work stealing schedulers have proven themselves to be very efficient for scheduling lightweight threads that block often (on IO or communication with other threads), and have been used with great success in both Erlang and Go. They address the scheduling problems discussed in the paper.

Thanks. I was not meaning to comment on whether Cantrill was right. His name comes up on this topic, and I wasn't sure whether it all stemmed from that paper, or if there were further complaints from him.
