That's interesting info, although I'm not affected by this particular issue.
Can you elaborate: should these caches be cleared on a reboot? Or do
they (normally) persist across reboots?
Is clearing this cache a part of updating via Software Update ie
during the "optimization" process?
If leftover caches are an issue, it's something else to put on the
checklist when t/s...
thx!
