# Note that this method is *always* called from a different
# thread than self.rpc's async thread. It is the only method
# for which this is true and requires special consideration!
# callAsyncNoSend is important here because:
# - callAsyncNoPoll isn't appropriate because
# the network thread may not wake up for a long time,
# delaying invalidations for too long. (This is demonstrateed
# by a test failure.)
# - callAsync isn't appropriate because (on the server) it tries
# to write to the socket. If self.rpc's network thread also
# tries to write at the ame time, we can run into problems
# because handle_write isn't thread safe.
