For every request,
a temporary file is created in /volatile to store the command output that is
sent back to the client. If the chunk parameter on the request is 0, the file
is deleted right before the command output is sent back to the client. If the
request does have chunk = 1, the file is retained so that the chunks can be
extracted from it and sent to the client. That file will be cleaned up on a
periodic basis. Currently that cleanup is set to occur once every 100 requests.
Files are cleaned up if they are not accessed within 60 seconds of being
created or are not modified or their status is not updated within 600 seconds.
