the change looks almost too neat for using a completely different command,
a bit fishy, but hey, if it works (roughly as fast) as the other one its
fine to me.

did you benchmark the both to compare for any bigger runtime difference?
E.g., some loop with a few thousands rados mon_command calls in perl for each
using HiRes timer to measure total loop time and compare?
I'd not care for a few percent, but would be good to know if this is
order of magnitudes slower - which I'd not expect, but its to easy to
check to not do so IMO.
