He is referring to Araneida and Hunchentoot. Hunchentoot received
significant rework sponsored by ITA. In particular, we added a single
threaded mode to Hunchentoot which is used to support a high
availability strategy based on Unix processes (i.e. there is a large
number of backend Lisp processes, each serving one client request at a
time, fed by a redundant load balancer configuration).
The multi-threaded request handling model of Hunchentoot is not
suitable for HA configurations as it does not have any thread resource
management built in. We have done some preparations to make it
possible to implement thread pools (and I know of at least one attempt
to do that), but I would in general try to avoid threading in
environments that require high levels of reliablility.
