I suggest using 'async', which is safe when used with gjournal. 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).
