Agreed on system threads vs libtask. Fibers of the sort libtask provides
(similar to GNU Pth) have some claimed advantages in efficiency in large
programs with lots of concurrent tasks, but for us, I vote for
Python-style use of OS threads with a Python-style GIL that we can
release to do long-running computations and recover from parallelism. (I
believe the existing concurrency branch runs under this model already,
but I'll have to take a closer look.) System threads also have much
better integration with the debugger and other development tools; fibers
have no offsetting advantages for us.
