I have added comments to _aixutil.py - but while doing so I came up with 
some thoughts re "special cases", where

a) the member is not in a archive (i.e., looking for a file)

b) the filename does not begin with "lib"

c) CDLL.LoadLibrary(name) succeeds

So, given that /usr/lib is default search path, and file FOO.so exists 
as /usr/lib/FOO.so - should find_library(name) return name, or None.

d) name = ../some/where/Foo.so; CDLL.LoadLibrary("../some/where/Foo.so") 
works - should find_library(name) return name

e) assume find_library("../some/where/Foo") returns 
../some/where/libFoo.so, or None - again, given that 
../some/where/libFoo.a does not exist
