If the library is built as shared then multiple applications can enter
its code space at the same time. Being non-reentrant most if not all of
these applications would break.

If built as a static library then each app has its own private copy of
the library, therefore there is practically no chance that multiple
applications using the library will interfere with each other.

Having said that, IMO the developer should be severely knocked for
having written a non-reentrant library in this day and age.
