Results do to some extent get collected asynchronously at the moment: if 
you run a procedure, tehre are three (relevant) steps: stagein, run, 
stageout, that can be interleaved with the same steps from other procedure 
invocations.

We've even had incorrect bug reports about this, on the lines of: I see 
that 100 jobs are being reported as completed by the job execution bit of 
the logs, but I see only one output file. What's been happening here is 
that the full permissible load for file transfer is being used for 
stageins, with stageouts happening much later ('asynchronously').

By batching, do you mean 'results from multiple procedure invocations 
going into a single file' ?
