f39e64d56a rt: Change the scheme used for terminating the kernel 
Instead of joining on the scheduler threads, instead keep a count of active
schedulers. When there are no more schedulers raise a signal for the main
thread to continue.

This will be required once schedulers can be added and removed from the
running kernel.

aee83d2ff1 rt: Only wake up all schedulers when no tasks are left 
At the moment there's not really any reason to be raising this signal,
since they schedulers wake up periodically anyway, but once we remove
the timer this will be how the schedulers know to exit.

25ae3d655c Rewrite spawn yet again 
The motivation here is that the bottom of each stack needs to contain a C++
try/catch block so that we can unwind. This is already the case for main, but
not spawned tasks.

abdb6cd71b Rewrite reap_dead_tasks to never grab the sched lock before a task lock 
Doing so contradicts the locking order used everywhere else and causes
deadlocks.

0cd607bcbd rt: Shutdown gracefully on failure 
When the kernel fails, kill all tasks and wait for the schedulers to stop
instead of just exiting. I'm sure there are tons of lurking issues here but
this is enough to fail without leaking (at least in the absence of cleanups).
