GOAL:
What are the benefits of using memory mapped libraries?
FIX:
The benefit of memory mapped procedure libraries comes from the fact that several users can share the same memory-resident copy of the r-code, thus using less total memory.
How much impact this has depends on how big the library is and how many users are sharing the same library. At one extreme you have one user, with no benefit at all and at the other you have hundreds sharing the same r-code saving hundreds of megabytes.
