With the separation of CENT and MIN_TX_FEE, it is now reasonable
to create change outputs between 0.01 and 0.0005, as these are
spendable according to the policy, even though they require a fee
to be paid.
Also, when enough fee was already present, everything can go into
a change output, without further increasing the fee.
When rescanning, if the scanned transaction is already in the wallet, it
is skipped. However, if someone sends a transaction, does not wait for
confirmation, switches wallets, waits for a block that contains his original
transaction, and switches wallets again, a rescan will leave his wallet
transaction (which has no merkle branch, so no confirmations) untouched.
