This is a bit minor, but what do you think about storing the previous exception
in L385, and then re-throwing it? This is most likely exceedingly rare, but it
might be possible that the reason why the previous call to `createInputStream`
failed was only transient, we're not 100% sure that we can reproduce the
exception by attempting it again.
