unserialize being slow ?

Presroi on irc pointed to an interesting bug report for PHP 4.3.10 : http://bugs.php.net/bug.php?id=31332

Some of our caches are stored in a memory cache (memcached), the apaches then just grab the datas and unserialize them. According to the bug report, the unserialize() function is slower than in 4.3.9 wich can explain the load trouble we are experiencing from time to time.

Looks like the issue is fixed since january 16th, we might want to try one of the lastest snapshot on one or two apaches and check if it fixes any issue.
