There is a DiskUsage attribute in the job ad, and I believe that it is
updated through the lifetime of the job, and that the startd always has
the most recent number available to it. You could use it as part of a
PREEMPT/KILL expression. 

I don't think DiskUsage tracks all disk usage though, only what's in 
the job's execute directory - so if you're writing to some sort of
scratch space that Condor isn't watching it doesn't help you.
