Description:
------------
I tried this on Linux 2.4.20, and mac os x server 10.3. Both servers have plenty of cpu and ram (linux: quad xeon 2.7 ghz, 2 gig of ram, macosx: dual g5 2 ghz, 2 gig ram), both doing almost nothing at the moment of the tests.

When we have a big session (~4 megs) under php 4.3.10, it takes up to 120 seconds to load the session with session_start.

./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql=/usr --with-xml --enable-versioning --with-zlib --enable-track-vars --enable-trans-sid --disable-debug

Difference from php.ini-recommended :
output_buffering = Off
memory_limit = 200M
error_reporting  =  E_ALL & ~E_NOTICE
display_errors = On
variables_order = "EGPCS"
register_globals = On
register_argc_argv = On
post_max_size = 200M
upload_max_filesize = 150M
session.gc_maxlifetime = 3660
session.bug_compat_42 = 1

gdb backtrace not relevant

Reproduce code:
---------------
<?
  session_id('12afec070d58ce9e64df6e458e097907');
  session_start();
?>

The sess_12... file is available here :

Expected result:
----------------
Loading in 3-4 seconds or less

Actual result:
--------------
Loading in more than 90 seconds
