... and I'm less than sure that it's a good thing. If nothing else, once the pieces of your program are passing descriptors around freely, you have created a barfball that will be impossible to split between several boxen if you run into scalability issues. Descriptor-passing is limited to a single system; you *can't* do that between e.g. components of a cluster. So it's not an unmixed blessing, just as overuse of shared memory segments, etc. They do have their uses, but that needs to be carefully considered every time, or you'll create a major headache a few years down the road. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
