A get which results in a huge response (cant think of anything that
fits there - I have some stuff i havent released yet which applies) will
also have the same. Note by "large" implies it will overflow socket
buffer (and a setsock to increase the size will delay the problem from
happening).
Note, that an overrun in a dump results in lost messages. Maybe we can
detect that and reset the cb pointers appropriately? Have to look at the
code.
