Increase space usage in memory
A target library might add space to a process.
A shared library's target file may have both text
and data regions connected to a process.
The text region is shared by all processes that use the
library, the data region is not.
Every process that uses the library gets its own private copy
of the entire library data region.
This adds to the process's memory requirements.
As a result, if an application uses only a small part of a shared
library's text and data, executing the application might require
more memory with a shared library than without one.
For example, using the shared C library to
saves disk storage and memory.
However, the memory cost for sharing all the shared C library's
private data region outweighs the savings.
The non-shared version of the library would be more appropriate.
