One possibility here is to give a callback function into the worker
function that gets called while the function does it's work.  Simple
example:

def do_work(arguments, callback=lambda msg: None):
    callback('Start processing.')
    for percent in xrange(0, 101):
        callback('finished %d%%...' % percent)
    callback('Done.')
