Parent daemons don't kill children when terminated?

[Dave Poeschel]

With Samba 3.0 releases, the master daemons no
longer kill their children when they terminate.

Was this a purposeful change from 2.2 behavior? 
(If so why?)

This is particularly relevant when managing multiple Samba
servers running on a single box (for example, highly available
"active-active" Serviceguard configurations on HP-UX).

Thanks,
