FileReaderSync is the synchronous counterpart of FileReader as defined in the HTML5 specification: http://www.w3.org/TR/FileAPI/#FileReaderSync.

Reading files synchronously would typically be done in a web worker so as not to freeze the application.  This is especially useful with GWT applications to create a java.io.Reader implementation that reads blobs using the File API.  This means that you can plug a blob reader into your favourite library that requires a Reader to run, eg: opencsv.  This is currently only possible using Gears' Blob.getBytes() which is also synchronous.

An example page is setup at http://rapilabs.com/test_sync.html
