Sounds like a reasonable measure. I wasn't aware we're exactly on
the boundary right now.


So then would it be ok to go w/ this?
@Andrew you mentioned something about "pulling an optional structure out into an explicit allocation", did you have something specific in mind? Would it be ok to do that for pl_time?
