Right, this doesn't belong here, I should add it later..

Mmh good point, I left it separate because the per-object monitors (later in the
series) do a bit more before calling the __da_handle_* functions (like some
potential allocation).

But it's probably not a big deal to let them do that in any case, considering
da_monitor_enabled() is false only during teardown or with monitoring off, and
in neither case a superfluous allocation should cause problems.

Thanks,
