/* it is expected that the main in this file will be called to test multiple 
process output at the same time a process is being deleted (font and bitmap server
disconnection.  There are  normally two instances of this process.  Two virtually
identical processes are required to ensure that the session ID is the same.

The first is with aThirdProcess set. This sets output to run in a loop until
the timeout is completed.  These values  are input via program arguments.

If aThirdProcess is false then only one font creation, draw text,
font deletion cycle is completed. The test code will then repeatedly run
this process with aThirdProcess set to false.
