The order of resident libraries typically affects only a few operations,
such as "OpenLibrary()".  If you OpenLibrary("dos.library"), you get
the library pointer back.  Calls made to dos.library use that library
pointer -- they don't have to scan the list again.

Rearranging libraries would be of dubious performance benefit.
