Even better.  If this is coming true, this is really really good news :-)

Indeed...

Well, that's another thing, not having everything modularized - but being
able to do things like "patch and restart the PIM process, and have a
downtime of 10 seconds for multicast" instead of "reboot, have 10 minutes
downtime for everything" when the next security hole in PIM, CDP, BGP, ...
is found is just very very very helpful.

Not having the machine crash when individual processes misbehave would
be even better.  SXF7 crashed on me some days ago when trying to do
CoPP with a "match protocol cdp" rule.  Now that is not a supported thing
- but *crash and reboot* is never the correct response to things a user
types in...
