Except for the added dependency you mean?
I'm not sure exactly what the capabilities of OpenMP are that would help
here, but most likely it would work. It wouldn't really change the
amount of work needed, though, since the main work is in shuffling
around the existing code paths to be amenable to parallel access in the
first place. A "dumb" parallelization (i.e., just locking around all
shared structures) POC yielded very little speedup because of lock
