UPDATE: Oh oh. This seems to be a configuration bug of some sort AND the documentation is out of date. The configure code now (since long before 2.2.9) tests if the architecture being compiled for is greater than i486 and if so, it provides you with "generic" hardware atomics -- ie, pthread mutex locking. It looks like it should have used assembly atomics, but someone goofed and got it the other way around. SO unless your package is specifically for the "i386" architecture, it will have use the pthread calls, not the assembly calls. If you have the APR "libtool" installed (search your filesystem for apr-1/../libtool) check the file for what it sets "host" to. If it's not i386 or not x86_64, I'm pretty sure you're not using mutexes.

I'm going to see what Apache developers say about this.

I am a little new to UBUNTU. When using the synaptic package manager, are the packages pre-compiled? I ask since since you say the "arhictecture being compiled for is greater than 486". Does syaptic download the package, check for the architecture and the compile or as I ask above are they pre-compiled.

apache::session::serialize::sybase

Apache::Session::Serialize::Sybase(3pm) 		User Contributed Perl Documentation		   Apache::Session::Serialize::Sybase(3pm)

NAME

       Apache::Session::Serialize::Sybase - Use Storable to zip up persistent data and unpack/pack to put into Sybase-compatible image field

SYNOPSIS

	use Apache::Session::Serialize::Sybase;

	$zipped = Apache::Session::Serialize::Sybase::serialize($ref);
	$ref = Apache::Session::Serialize::Sybase::unserialize($zipped);

DESCRIPTION

       This module fulfills the serialization interface of Apache::Session by taking the data from Apache::Session::Serialize::Storable and
       modifying it to work with Sybase IMAGE fields. Note that you do not need to quote these values before inserting into the database, and that
       if you are using DBI::Sybase, you cannot use the data in a placeholder. If you use Apache::Session::Sybase as your session class, this will
       all get taken care of.

AUTHOR

       Apache::Session::Serialize::Storable was written by Jeffrey William Baker <jwbaker@acm.org>; the Sybase-specific data manipulation was
       written by Mark Landry <mdlandry@lincoln.midcoast.com> for use in an earlier version of Apache::Session::DBI::Sybase and placed here by
       Chris Winters <chris@cwinters.com>.
