bug#2268: 23.0.90; Sometimes becomes very very slow to respond

Hi,

Sometimes (browsing a huge file or using ido for finding a file) and
randomly emacs hangs for some seconds, consuming 100% of my CPU. I
have to wait and it responds again. In the meantime, nothing works.

This did not happened before Romain Francoise updated his repository
some weeks ago with the pretest version (http://emacs.orebokech.com).

Thank you for making Emacs a great tool
