Sadly, there's no good way to do this in HTCondor today -- the value of the

DOCKER_EXTRA_ARGUMENTS is always a fixed string, and it is not evaluted 
in the context of the job or slot ad. However, what we do here at CHTC 
is set --shm-size to a high value. HTCondor always runs docker jobs 
with a memory limit, and the memory used by /dev/shm counts against 
that, so there should be little downside to setting -shm-size high for 
all jobs.
