> In various places we catch Throwable and suppress it, usually in exception handlers where
we want to just throw the first exc we had hit.
> But this is dangerous for a thread interrupt since it means we can swallow & ignore
the interrupt.
> We should at least catch the interrupt & restore the interrupt bit, if we can't rethrow
it.
> One example is in SegmentInfos where we write the segments.gen file... there are many
other examples in SegmentInfos too.
