Finally got around to installing Snow Leopard (10.6.3) and I'm wondering
what the heck this webkitpluginhost thing is in Safari that constantly
wants to call out. You've probably discussed this before but I did not
find it. Everything else seems to be fine and peppy.

In short, Safari/WebKit on Snow Leopard uses a separate process to host
plugins. If a plugin crashes, Safari doesn't go down with it. Flash is
the main guilty party.

If you are seeing vast memory and/or CPU usage from webkitpluginhost,
stop visiting web sites which use Flash, or install something like
ClickToFlash so you have some say in the matter.

In Leopard, any memory and CPU usage due to Flash is shown as part of
the Safari process.

Thanks. I did a google search previously but did not find out how to
set Little Snitch (2.2.2) for this webkitpluginhost. I've been using
ClickToFlash, which is great, for some time now so Flash has not been
running. It seems there are few web sites not using Flash these days so
I can't imagine how people avoid it if they aren't running ClickToFlash
or something similar. Safari has crashed (spinning beach ball) several
times for me since I installed Snow Leopard yesterday--- all seemingly
in conjunction with those frequent webkitpluginhost messages.
Everything else seems very stable and fast, fast, fast.
