memcache woes in Ubuntu Intrepid.

Seems like Ubuntu Intrepid uses a beta version of memcache module for PHP. This has caused a number of grief in my Drupal 5 + cacherouter + memcache development site: e.g. http://drupal.org/node/245341#comment-1397634
Specifically, this is a bug where memcache::delete($key) does not work unless you specify the optional timeout value. This is uncovered after lots of testing and cross checking using:
<?php
$memcache = new Memcache;
$memcache->connect('localhost', 11211) or die ("Could not connect");
$version = $memcache->getVersion();
echo "Server's version: ".$version."<br/>\n";
for ($i = 0; $i < 10; $i++) {
print "<br>$i:";
$ret = $memcache->add('foo', 1, 0, 2);
if ($ret === false) {
print "can't add. ";
sleep(1);
} else {
print "<b>works</b>";
}
// In the bugged version, you'd need
// $ret = $memcache->delete('foo', 0);
// to work properly. So to exhibit the bug:
$ret = $memcache->delete('foo');
}
print "done";
phpinfo();
