'''Short description'''

I'd like to speed up page save operations that involve sending an email to users watching/subscribed to the page being edited.

The mile-high idea is to take the user-defined regexes for page watch subscriptions out of individual user preferences, and maintain a global list of unique of regexes, with a list of users per regexes.

Then a page save could use the global regex list to figure out which user to notify, rather than pulling iterating over all users' prefs to get a the list.

This feature request will mainly benefit wiki's with a large user base, such as the [[http://fedoraproject.org/wiki/|Fedora wiki]].

'''Implementation'''

[[http://dan.drown.org/fedora/compare-storage.html|Example implementation for Moin 1.5.8]].  The implementation also compares the timing between the 1.5.8 code and the suggested replacement.

'''TODO'''
 * read irc channel logs about other ideas (esp. respective authoritative data storage, caching)
 * own unit tests showing it works
 * other tests already there not failing (including the pep8 sourcecode test)
 * patch for 1.7
