The cwd lookup was taking 2% of a flamegraph I was looking at.

For what length of time is the cwd cached? Is there a danger of inconsistent behavior if it gets changed?

It should only be using the initial cwd for the main module, which won't have its cwd changed by this point (unless something outside the process races to change the cwd after the initial cwd is stored, which this actually works more as expected now)
