So you're saying if you start a Tcl application (e.g. gis.m) from a Unix 
shell, and then set an environment variable within the Tcl application, 
that the shell kind of inherits it backwards and commands run from there 
will be affected by the changed environment? I didn't think of that - I 
suppose it would be better if Tcl allowed you to specify environment 
variables that applied only to it and commands spawned from it.

But I suppose anyway you can work around it in this case by setting 
GRASS_RENDER_IMMEDIATE before running d.font -l and unsetting it
