Yeah, but it still seems to scan the whole file, in place.

Yeah, but it still seems to scan the whole file, when updating the
X-status. Oops i'm repeating myself <G>

There's no other explanation. If Yarn just searched the offset of read
messages and updated the xstatus just on the one changed it would be like
lightning... instead we see longer delays proportional to the size of the
folder... hence yarn is obviously scanning the entire folder when it
updates the X-Status. It will update the X-Status if you "read" any un read
messages (ie. it had no mark before, but then gets "R" when you leave the
message).
