Yeah, I was surprised too.  I have to wonder if we had some reason for
that omission, but I didn't find any such documentation...

Sure, this should give the same info as probefunc() would directly in
the probe, though symname can be delayed.  So long as you don't care
about the rest of pp(), like source location, then you could print each
IP at probe time and symname(ip) later to decode them.
