FWIW, 0..concurrency numbering of the first helper request field is a
very natural (but no longer correct) interpretation of that field name
-- "channel ID". IMHO, Squid documentation should be rewritten to use
"transaction ID" instead. Pull requests and wiki updates are welcomed.

What used to be a small channel ID from a 0..concurrency interval, is
now an ever-increasing/unique (within a helper instance scope) 64-bit
transaction ID. There is (a somewhat veiled IMHO) explanation about that
in Squid v4 release notes:
