rust_task is using the word limit it two ways, so one has to change.

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).

4ef1ec580a Do all runtime calls to getenv at initialization 
getenv is not threadsafe and (maybe as a result) it's randomly crashing with
CFLAGS=-g and RUST_THREADS=32. Calls from rust code are still on their
own.

5302cde188 Made task threads wait instead of sleep, so they can be woken up. This appears to give us much better parallel performance. 
Also, commented out one more unsafe log and updated rust_kernel.cpp to compile under g++

62bc6b5113 Per-thread scheduling. Closes #682. 
Tasks are spawned on a random thread. Currently they stay there, but
we should add task migration and load balancing in the future. This
should drammatically improve our task performance benchmarks.

3ae4dcd41e Lots of work on memory tracking and channels. 
We're trying to get closer to doing correct move semantics for channel
operations. This involves a lot of cleanup (such as removing the
unused sched parameter from rust_vec constructor) and making
circular_buffer kernel_owned.

Added tagging for memory allocations. This means we give a string tag
to everything we allocate. If we leak something and TRACK_ALLOCATIONS
is enabled, then it's much easier now to tell exactly what is leaking.

4738cf83b0 Move the responsibility for process failure from tasks to the scheduler 
When the root task fails the process fails. Failures on other tasks propagate
up the task tree. Failures on non-root tasks without parents just
(theoretically) unwind and disappear.

bc5d6aefda Added a task wakeup callback. Closes #599. 
The callback happens when a task moves from the "blocked" state to the
"running" state. The callback is also inherited by child tasks. There
is currently only a native API.

This code hasn't been heavily exercised yet.
