Does the condor implementation do the command line tool launching/scraping technique or is it actually doing something more efficient (like talking DAEMON_CORE, parsing logs, inserting itself into hooks within condor and talking its own language, something else)?

I ask because the current approach I am forced into is error prone, slow (significantly, I am forced to throttle things heavily to avoid nuking the schedd) and occasionally spirals out of control. If I can replace some of it with this that might help. Alternatively I can see about borrowing ideas from how you do the sub process management.

Note: I haven't gone 7.6 series yet, it may be that that improves things sufficiently that I needn't bother, but you piqued my interest.

Thanks,
Matt
