Comment (by pramsey):

 No, the initGEOS() call checks the global "handle" and if it's non-null is
 creates one on the heap. Subsequent calls find a non-null value and do not
 bother. So that first initialization is shared by all subsequent calls to
 initGEOS by that backend. Which could be a lot of calls. This is why
 sticking a finishGEOS at the end of every function call is not necessarily
 a grand idea.
