when can we tsleep() ?

Hi,
this is related to kern/39725. We have cpu_intr_p() which tells us
if we're in interrupt context or not. But there's other cases where
it's not safe to call tsleep (e.g. from soft interrupt context, maybe
others). If there a function or check that can tell us if it's safe
to use tsleep() or not ?
