My current solution to this problem is to change this call to krt_ifread()
to a call to krt_ifcheck() instead:

    krt_ifcheck();

The krt_ifcheck routine schedules a task that runs krt_ifread, thus
getting around the problem of the multiple calls to the non-rentrant
krt_xaddrs() function.

However, it strikes me that it would be desirable to schedule the
job a few seconds in the future, rather than running it right away,
so that if there are a bunch of updates happening at once, we can
reduce the cost of the scans. Does anyone know how to do this?

And while we're on the topic, is there any internal documentation
available for gated? The `internals guide' that comes with 3.5 beta
4 is one page that says essentially `this doesn't exist.'

It's become apparent that this has nothing to do with NetBSD, so
I'm redirecting replies to just the gated list and me.
