Purpose of supervising temporary children?

[David Mercer]

What is the purpose of supervising temporary children?  I know you're not
supposed to have rogue unsupervised processes running around in your OTP
system, but is there that much danger in having such rogue processes if they
are linked to supervised processes?  Is the supervisory role just smoothing
off some of the rough corner cases of plain old linked processes, or is
there more to it than that?

 

Please advise.  Thank-you.
