Okay, I hope people read this. Send me a note at ian.nelson@echostar.com if you wish to discuss it.

Here is my question. What the hell good are SysV Queues? The Linux kernel limits them to 16. So you have a software resource that is limited to 16 instances. That just seems low. With such a small number of them they are a valuble resource, how do you decide who can and can't use them?

The logical next question is what the hell good is SysV IPC at all? Anyone? Anyone? If you want to really ponder this, what you need to do is architect a system, a complex one, and use SysV queues for IPC, only then will you have the true state of mind to enjoy this problem. Former Windows hacks think they are the logical choice for IPC. Fortunately you can bump a constant in the kernel and ramp the max up to 64 or something but that feels like a bandaid for a bullet wound.
