Code review comment for lp:~matej-sekoranja/epics-base/pcas-variable-length-arrays

Previously the CA client library converted monitor requests with zero size to mean all elements; the client knows the maximum array size since that information is sent out as part of the initial channel connection process. Would it be hard to change the pcas behavior so that an unmodified server application would send the max number of elements for the channel instead of just one, in both the get-callback and first monitor cases? I think that would be safer.
