Don't want to pull anyone into an NPM here, but we could have a tiny egg 
to abstract that away ("we" = anyone willing): exports 
current-process-milliseconds if >=5.3, otherwise renames 
current-milliseconds if <5.3. Shouldn't be too hard and egg authors are 
no longer inconvenienced with writing the cond-expand.
