pc_server times out; disconnects user.

Description:
We find that the pc_server is timing out the client -- and disconnecting the user -- when the user doesn't hit Enter for a minute or two.
Resolution:
There's a PC_SERVER_TIMEOUT value in pc_server_defaults, but it is used to determine the max time in seconds in which the server attempts to handle a single transaction. If this time is exceeded, the message "Server failed to execute request after nn seconds" is issued. So this variable does *not* come into play in the not-hitting-Enter situation.
The $aleph_proc/pc_server has PC_CONNECTION_TIMEOUT and PC_IDLE_CONNECTION_TIMEOUT values. Neither of these timeouts results in a message to the user; it seems that they operated behind-the-scenes. As of July, 2016, we are still studying their effect.
In this case the disconnection was being done by a timeout value in the *firewall*. Setting that higher corrected the problem.
