I'm taking a look at
<http://common-lisp.net/project/cmucl/doc/cmu-user/extensions.html#toc46>
and i have some questions about the :status-hook.
It is a function that gets called automatically when my child process's
status changes. What happens if i have 100 child processes and many of
their statuses change at about the same time? Do i need to worry
about this? What if the status changes before i get finished
creating all my processes? What if the status-hook function is
running, and before it finishes another processes status changes?
Do i need to implement a locking mechanism myself to handle this
situation?
