It's not a big difference, just that we tend to keep such data in the
context.  I mostly don't like the new struct being passed by void-*
and then suffering unprotected dereference in the embedded-c
functions.

(Extra memory consumption is negligible - one more word per CPU.
Initialization time/space could be further reduced if
per-probe-point-type data were gathered into unions.)
