[Spread-users] Leader crashing often

It is not necessarily the number of members in the group.  The crash is
related to the number of members * the size of the private names
associated with that group.  This can not exceed the vector space that
sends this information out which will hold maximum
 
100 ( num_elements ) * MAX_PACKET_SIZE

But does this relate to the total number of members summed over all
groups, or 
only the number of groups a certain message is directed to? Because we
might 
have a high number of clients which are in no group (aside from their
private 
group of course), but we certainly have no group with 100 members.
