One thing I've wondered about: is this thread safe? Is there a chance
that between the first and second statements something will change the
result of the global variables?

I tend to use the more verbose:
.. pid, name = str.match(/^(\d+)\s+(.*)$/).captures
or
.. pid, name = str.scan(/^(\d+)\s+(.*)$/).flatten
