fa88d15d63 remove unneeded assert, move get_task_tls to sched_loop 2012-04-02 14:21:09 -07:00

33a949eed6 Add global rust_get_current_task
Previously two methods existed: rust_sched_loop::get_task and rust_task::get_task_from_tcb. Merge both of them into one, trying the faster one (tcb) first, and if that fails, the slower one from the tls.

4c4a2320eb rt: Make rust_port_detach less contentious
It still utterly dominates some benchmarks with busy waiting, but at least it
doesn't create lock contention while doing so.

14306756b4 rt: Always delete task stacks on the task thread

less prone to future errrors.

028af5cb6c rt: Change the lifecycle of tasks and schedulers for various reasons
This is in preparation for giving schedulers their own life cycle separate
from the kernel.

Tasks must be deleted before their scheduler thread, so we can't let the
scheduler exit before all its tasks have been cleaned up. In this scheme,
the scheduler will unregister tasks with the kernel when they are reaped,
then drop their ref on the task (there may still be others). When the task
ref count hits zero, the task will request to be unregistered from the
scheduler, which is responsible for deleting the task.

Instead of having the kernel tell the scheduler to exit, let the scheduler
decide when to exit. For now it will exit when all of its tasks are
unregistered.
