memcache 7.x-1.0-beta3

The 7.x-1.0-beta2 memcache module was released prematurely, and resulted in a serious performance regression. The 7.x-1.0-beta3 release fixes this performance regression.

NOTE: The 'memcache_wildcard_timestamps' variable is no longer used by the memcache module in 1.0-beta2, however the module has no install file to automatically clean this up. It is safe to delete this variable from your database, either manually or for example by calling "variable_del('memcache_wildcard_timestamps');" within a drush script. You should only do this after deploying memcache 1.0-beta3+. This is not a requirement, only a cleanup suggestion. If in doubt, ignore this.

Bug fixes:
