i.e. in the debug.log extract below, at 18:02:59 the tx is added to the askfor queue for node 6, the tx then comes through from node 2 and is rejected, but it stays in the askfor queue for node 6 because at 18:04:58 a getdata tx is sent to node 6.
The tx is also requested from other nodes, but this is because the inv for the tx comes through after the tx is rejected and the node doesn't keep track of recently rejected txs. This would involve a different fix (e.g. remembering rejected txs for a minute after rejecting them) - I've already raised a separate issue for this.
