IMHO the default is way too low (and undocumented as far as I can
tell.) 8 is also arbitrary, but seems like a much more reasonable
value in most cases, going over 4 broken processes is not hard if you
have bad luck and a long running box, going over 8 broken processes is
considerably harder, like all magic numbers, all matter of judgement
and experimentation.

Note that others have also reported broken procs 'vanishing', probably
because they didn't know there was a limit and that the limit was so
low.
