Faking X Display for IDL Bridge [message #72430]

Hi,
I just had this great idea of forking IDL jobs on my 16-CPU server
using the IDL to IDL Bridge. The code runs great from the command line
but using a UNIX cron job I get the error message "IDL_IDLBridge:
Unable to establish X Connection." To late did I understand the the
help that reads:

"Warning: On UNIX systems, the IDL_IDLBridge requires that the DISPLAY
environment variable be set to a valid X Windows display. If no
display is available, execution of the IDL_IDLBridge will halt, with
error messages that include:IDL_IDLBridge: Unable to establish X
Connection."

The requirement for an X display seems silly, as my code does not
display anything. Is there a way to fake the existence of an X window?
Or did I just wasted my time coding this feature?
