I was reading the docs
<http://julia.readthedocs.org/en/latest/manual/control-flow/#tasks-and-events>,
and it seems to me that it's saying I can use tasks to run multiple
subprocesses at once. E.g., if I have some long-running subprocesses such
as `sleep 10`, I should be able to wrap each in a Task and use the inherent
wait() command that running each subprocess would entail to switch to
another task and kick off another subprocess. Is this correct? If it is,
can someone provide me a quick example? I can't seem to get this to work,
but I've never used Tasks before so that's hardly surprising. ;)
