[Zodb-checkins] SVN: ZODB/trunk/src/ Merged Deiter's branch that provides object-size-based object cache

[Sidnei da Silva]

Something doesn't look quite right here. Previously the comment said
'only need 62' but the sum was actually 60. So assuming those extra 2
bytes are going somewhere else, the comment is still wrong, it should
say '68 only need 66'? And also the next line should read 'Even a
ghost requires 68 bytes' now?
