the Memcache::delete(key) function is broken on several combinations of memcached+pecl-memcache combinations.
pecl-memcache 2.2.5 + memcached 1.4.2 - Memcache::delete(key) WORKS
pecl-memcache 2.2.5 + memcached 1.4.3 - Memcache::delete(key) DOES NOT WORK
pecl-memcache 2.2.5 + memcached 1.4.4 - Memcache::delete(key) WORKS
pecl-memcache 2.2.5 + memcached 1.4.5 - Memcache::delete(key) WORKS
pecl-memcache 3.0.4 + memcached 1.4.2 - Memcache::delete(key) WORKS
pecl-memcache 3.0.4 + memcached 1.4.3 - Memcache::delete(key) DOES NOT WORK
pecl-memcache 3.0.4 + memcached 1.4.4 - Memcache::delete(key) DOES NOT WORK
pecl-memcache 3.0.4 + memcached 1.4.5 - Memcache::delete(key) DOES NOT WORK

According to the documents, $timeout is not required, but for me if I did not include it regardless of value, it fired an error. I made a simple fix for it.
<?php
class memcache_tools extends memcache
{
public function delete($key, $expire=0)
{
parent::delete($key, $expire);
}
}
?>
This will force it to behave as it should regardless of version.

I could not get the delete to work properly, so I ended up trying the 'set' method and setting the timeout value to -1.
<?php
$memcache->set('index', 'deleted', 0, -1);
?>
It solved my problem with the delete method.
(using memcached 1.4.5 and pecl-memcache 3.0.6)
