More likely that those requests are ones where the client actualy
disconnected. Your quick_abort setting configure Squid to keep going
after a disconnect. This happens outside the pooling since there is no
client to pool.

It *might* be a client doing some tricky request behaviour. You could
pick this up by a) these requests are *all* MISS requests (indicating
only-of-cached header preventing slow network access), or b) these
requests following an earlier request within a very short time
(indicating a leach re-attachment once the above pool detachment has
been done by Squid).
