You nee$ That certainly would qualify as the stupid thing I was doing which I figured must exist! As for "dispatch[ing] to another kernel thread"...can a soft-int create a kernel thread, or do I need to precreate the thread and have it in my back pocket so I just need to wake it up when the callout fires? Might this be a good use case for workqueue(9)? The manpage makes it look as though that would manage the thread(s) and queue(s) and such for me, which feels like a significant benefit in this case. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML [email protected] / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
