Actually, it's something subtler than that. It must depend on the
actual data, because now when I tried it again, it worked with 'g'
too. I hadn't saved the old perf.data that caused the lockup (it got
overwritten by the non-g test), and now when I try to re-create it it
doesn't hang on the result.
So it's probably some very specific data pattern that causes it.
(And I don't know if it's a hard hang - it could just be something
_very_ slow. But we're talking half a minute kind of slow).
