+The "forks" pragma allows a developer to use threads without having to 
+have a threaded perl, or to even run 5.8.0 or higher. There were a number 
+of goals that I am trying to reach with this implementation.
+
+The standard Perl 5.8.0 threads implementation is very memory consuming, 
+which makes it basically impossible to use in a production environment, 
+particularly with mod_perl and Apache. Because of the use of the standard 
+Unix fork() capabilities, most operating systems will be able to use the 
+Copy-On-Write (COW) memory sharing capabilities (whereas with the standard 
+Perl 5.8.0 threads implementation, this is thwarted by the Perl interpreter 
+cloning process that is used to create threads). The memory savings have 
+been confirmed.
+
+You should be able to run threaded applications unchanged by simply making 
+sure that the "forks" and "forks::shared" modules are loaded, 
+e.g. by specifying them on the command line.
