share packages

[Jose L. Hernandez]

Hi,
 
I'm working on a server application based on the boss-worker threads model.
My problem is that the worker threads use a lot of packages, and the memory
usage is too high.
Is it possible to share the memory used by the modules? I don't understand
why it is getting cloned for every thread I start. 
 
Something like  "use MyPackage : shared; " would be nice...
 
Thanks
