PHP user session handlers

Done, I've just tested on PHP Version 5.2.0RC7-dev (today's snapshot)
and get the same result. The code is:

session_start();
$_SESSION['testing'] = $contents;
session_write_close();

unset($_SESSION['testing']);

session_start();
$newcontents = $_SESSION['testing'];
session_write_close();

There is a php file prepended to all code executions that sets up the
custom handler and it works for the first session_start, but on the
second call to session_start, I get:

Fatal error: session_start() [<a href='function.session-start'>function.session-start</a>]: Failed to
initialize storage module: user (path: /tmp/php_sessions)

i.e. It still knows that it's a custom defined handler, but the
references to the functions are gone. If I make a call to
session_set_save_handler after the first session_write_close, the
problem goes away. Of course, this isn't practical for a large number of
sites.

Hi guys,

Just wondering what the status of the user-defined session handlers is?

I don't think it makes any sense to ask such questions on the list,
for the answer in most cases is "they are doing fine, thank you".
Just grab the latest snapshot, test it and report any issues you see.

I've tested with 5.2rc4 and there is an issue that the references to the
user functions get erased when the user calls session_write_close or
session_destroy. This means that the system reverts to an alternative
handler.

Any idea if this issue has been resolved or if not, how it could be
resolved? It basically makes large-scale user-defined session handlers
impossible (for general website handling). It has been discussed
previously, but no solution has been proposed as of yet.
