Multi-user aspell usage.

I have a server app that is used concurrently by several users.
I plan on instanciating a speller for each user, with their personal 
preferences.

I'm hoping that that all the instanciated spellers will use the same 
read-only master lang dictionary.
Is this the case?

eg.
If 5 userers all use the en_US lang dictionary will I get 5 loaded 
copies of the dictionary or hopefully just one?

Thank,
