Extend [1,2,3] to avoid:
hook 1: spawn ---------------> reaped
hook 2: spawn ----------------> reaped
hook 3: spawn -----> reaped
and explicitly require:
hook 1: spawn --> reaped
hook 2: spawn --> reaped
hook 3: spawn --> reaped
Folks who do want parallel execution are free to use a parallelizing
wrapper:
hook 1: spawn ---------------------------> reaped
child 1 -----> reaped
child 2 ---------> reaped
child 3 ---> reaped
Although that cuts both ways (with parallel hooks, folks could always
use a single hook with a serializing wrapper). Still, I'd guess most
current implementations are already taking the serialized approach, so
it makes bundle-author life easier if we are explicit about that.
