Can I ask how you are using transactions? A lot of software edits a shapefile "in place"; GeoTools tends to write out the whole thing again during the commit (into a separate file, and then rename the files to swap them; and then remove the original).
There are seperate read and write locks in the shapefile code; so the writing out should wait for all the readers to be finished before this occurs.
