+ * This function might fail! I decided that it didn't matter. We are too late

+ * out this process's current cap set along with the fcaps from the PATH record
+ * and use that to come up with the final set. Yeah, its ugly, but all the info
+ * is still in the audit log. So I'm not going to bother mentioning we failed
+ * if we couldn't allocate memory.
+ *
+ * If someone changes their mind they could create the aux record earlier and
+ * then search here and use that earlier allocation. But I don't wanna.
