now the data captured while encoding WAV is not lost

this is especially helpful when you are sending chunks of wav to server.

Since the worker lives in a single thread and there are no asynchronous operations in recorderWorker.js, under which circumstances, data is lost? I would expect that as soon as encoding starts, everything else in this worker is blocked and the messages containing data are piling up in the browser's event queue, thus if a clear is the first item in the queue, all data is added to fresh buffer-holding arrays. Only if the clear is issued somewhere later, data is lost.
