yes, in shared memory, to be more specific.

not necessarily - you use the function only only if you want to delete 
the AVPs at some specific point in script. AVPs are transaction/message 
persistent , and they are automatically deleted when the transaction / 
message is deleted (AVPs are part of transaction/message)

those are just names of AVPs, not instances of AVPs

As said, AVPs cannot cumulate in memory as they are attached to 
structures (transactions/messages) that are deleted.

If you get errors on on running out of memory, please read and follow:
