0.9.1 & history.length

[Joel Bierling]

0.9.1 has disabled access to history.length.  How is the length of the
history a security threat?  Is there any work around?  I have a web app that
saves the current history length and then there is another button that can
return to that particular page using go(history.length -
previoushistorylength).

Thanks,
