This is a thing I've always wanted to ask - why is it safe? :)

I guess it comes down to what exactly does async means - since it's a 
file system flag I've always considered that it delays data output from 
the file system layer to the lower layer (GEOM) - but in that case it's 
definitely not safe. At least my idea for gjournal is to use it with 
"sync" flag (and get the performance by writing everything sequentially).
