Which documentation is giving you that?
'concurrency' is the limit on number of requests Squid has in flight to
The channel-ID is an opaque value that should be unique for each line
sent to the helper.

The on-persistent-overload=ERR option allows for more than the N of
concurrency=N requests to be not-yet-responded in the helper at once.
Squid does not tell the helper which lookups it has given up on and
produced the ERR for - it just sends another lookup.
