It could be fast, but it couldn't be faster than doing "cat mailfile", 
which is basically what maildir clients do.

Sorting could be completely done by SQL server with ORDER BY, but 
threading would require just fetching a few headers and doing it 
internally. Dovecot 1.0's cache file btw. keeps the commonly used 
headers stored in it.
