It makes no sense to be using something calld start() to perform
shutdown/stop oeprations.

The eCAP stop() method is perhapse better, although that is documented
as only being stop until a further start() is called so not a full shutdown.

The retire() method seems to be another option although I dont quite
understand its documentation myself. There is also the two configuration
methods. It may make sense to reallocate or release unnecessary memory
when finishing a reconfiguration.

NP: I cant find any explicit eCAP closure code in Squid. Perhapse the
object destructor is the best place for shutdown cleanup.
