Description:
------------
memcache version 3.0.3 and memcached version 1.3.2.

How can I use UDP for 'set'.
How can I just use 'udp' connect memcached.

Reproduce code:
---------------
$memcache = new MemcachePool;
$memcache->connect('192.168.0.169', 0, 11223);
$mem_key = 'test_package';
$memcache->set($mem_key, 'sajkdghlghasldghsalghaslgh');
$re = $memcache->get($mem_key);
var_dump($re);

Expected result:
----------------
Warning: MemcachePool::connect() [memcachepool.connect]: Can't connect to 192.168.0.169:0, Failed to parse address "192.168.0.169" (0) in /data/local/apache2/htdocs/test.php on line 6
bool(false)

The fix for the connection is simple.  The problem is that there are assumptions in the code that rely on TCP connections.  Trying to use a UDP connection is completely unreliable.

I will leave this ticket open until all UDP issues are fixed.

$b = new MemcachePool;
$startTime = microtime(true);

$b->connect("udp://127.0.0.1",16222);
$d = $b->get("testKey");

var_dump($d);
====================
the result is false 

and some error
SERVER_ERROR multi-packet request not supported

what problem?

The official bug tracker for PECL/memcache is now at
<https://github.com/websupport-sk/pecl-memcache/issues>.

So, if this is still an issue with either of the current memcache
versions (4 or 8), please file an issue there.
