I suspect that reenabling interrupts becomes "safe," in the words of the infamous references, when it is no longer possible for *that specific* interrupt to be generated *again.* For instance, if you need to have an especially long- duration serial driver, you would need to block interrupts from that source specifically before reenabling interrupts generally, then reallow interrupts from that source when finally done. Of course, if your code manages to be reentrant, these worries don't apply. (-: -- CRANBERRIES! ALBUQUERQUE!
