If you want to use the async io code rom anywhere, say, logfile writing, you're _going_ to have to do write combining or your write queue is going to quickly blow out to a stupid size. The store IO interface really assures us there's only one outstanding write per object at a time, unless something whacked has change which I haven't yet picked up on. Funnily enough, if you check out src/disk.c, you'll find some stuff which was done many, many, many moons ago to deal with async write combining. Just 2c. Yes, it'd be nice to have true async writes for logfiles and such. But you're going to have to do write combining. Adrian
