logical units unavailable [message #9014]

I have a program which spawns some c-code, then reads its output. I
use the "spawn" command with /get_lun, as in:
IDL> spawn,cmd,unit=lun,/get_lun

After I've read the results, I use "free_lun" to free the logical
unit:

IDL> free_lun,lun

I find that when I've run this spawn that I get the error:

% SPAWN: All available logical units are currently in use.

Which is crazy, since every use of a lun frees it also. What is up
with this? Is there any way to release all logical units without
exiting IDL and loosing all the work I've done?

Thanks,
Daniel Williams
