# a callback when the translation is done. The request handler that processes the callback would, in turn, write to the cache
# so subsequent cacheGet() calls would return the now completed translation. I'll add this option in an update in the next week
# or so, but am sticking with synchronous polling for now (its simple and doesn't depend on an App Engine specific resources).
