Since the actual maximum array size that can be sent is the smallest of 
both the client and server's settings it's possible to set this to a 
giant number on your client workstations and gateways where you usually 
have the least idea what to set it to (our Unix shell configuration sets 
this at the same time as setting EPICS_HOST_ARCH).  For each IOC you 
still have to work out how big your largest array field is and set the 
value appropriately, but at least this limits the scope of the problem.

I know Jeff has plans for removing this limit in the future, but it 
relies on completely replacing GDD with Data Access, which is a fairly 
major change.
