I've often wondered why grants and revokes require exclusive pins.  Why would a 
grant have to invalidate cached metadata for the object?

Hello list,

When I grant execute on a function to a user, the session is wating on
'library cache pin' wait event. I have waited for 20 min. still session
waits on the same wait event.
Any ideas?
