For the lock to be useful any and all mutators would have to aquire it, as
well as anyone reading the shared variables, since we need to keep anyone
from changing the internal structure of the PMCs, as well as the PMC
metastructure, while we're running a scan. (And this gets more interesting
if we have multiple interpreters each of which share some data with other
interpreters but aren't necessaarily operating in a fully shared
environment)
