I suspect it is because renderString might well want to do other
operations in order to construct the string, and the result may
not be immediately available.

You could do somethign like:
There is also a helper function that you can use:
s = page.renderString()
from twisted.trial.util import wait
s = wait(s)
though I am not sure how advisable it is to use that, depending on
what exactly it is you are trying to do...
