Summary:                    [patch] app_festival hangs on reading from spawned
subprocess
Description: 
Due to an invalid file descriptor (one that's already closed) being
referenced for writing in the subprocess that's spawned to feed the
festival output to the channel, app_festival blocks on trying to send voice
data to the connected channel. This kills the Asterisk session completely.

The attached patch fixes the issue and adds some debugging statements to
app_festival for checking that it now works.
