Only on the submitting side right now. I considered minimums on the 
execute side, but never worked it out completely.

# Base RequestMemory to use if not provided by user
RequestMemory = 1024
SUBMIT_EXPRS = RequestMemory

request_memory (translated into the RequestMemory attribute on your job) 
is actually an expression, not just an integer. You could,

request_memory = ifThenElse(TARGET.Memory < 35000, TARGET.Memory, 35000)

or something like that anyway.
