EXECUTE is not created by Condor - it's the directory that we create 
CONDOR_SCRATCH_DIR in.

Condor will not start if there is not an EXECUTE directory. When Condor
wants to start a job, it will create a new directory in EXECUTE, and
delete it when the job is done.

The job starts in the CONDOR_SCRATCH_DIR, unless the job lists somewhere
else to start, but I still think Condor creates the CONDOR_SCRATCH_DIR.
