In addition to my questions before, be aware that indeed it could be 
normal owner as "condor" temporarily, but it shouldn't stay that way 
long (thus all my questions in previous post).

HTCondor does a stat() on the $(EXECUTE) directory to determine how the 
job sandbox should be created.   If it is world-writable, we do a
mkdir() as the user. If it is not, we do the mkdir() as condor then 
chown() it over to the user or slot-user, since we have no realy choice...

So if you are willing to make the $(EXECUTE) directory world-writable, 
HTCondor will avoid the chown from condor to user step.

Another couple quick questions:

- is your $(EXECUTE) directory on NFS with root-squash??

- do you have PRIVSEP_ENABLED=True in your condor_config on the execute 
nodes??? (note: PRIVSEP support in HTCondor is deprecated, unsupported, 
and soon to be removed from the code....)

regards
Todd
