So there is nothing there can be done about that? Not even in theory?
This is a major limitation imho. 
So the database is locked for writes during the sync right? But akonadi knows 
which message to sync ... It could do that and commit changes to the database 
when lock is over, no? What are the special things it does have to write to 
the database which is locked? I suppose the read/unread flag in the first place 
and for imap the message contents right? Couldn't the message you are trying 
to read be fetched into a buffer that is queued to commit to the database 
later?
