I wonder what it is up to (or even how to benchmark it).
Clearly you have to do a VOP_LOOKUP (or whatever netbsd calls it)
for each shared library, but the extra mmap() calls shouldn't
take too long I wouldn't have thought there was that much
O(n) stuff to do....
I wonder how to profile it - would probably be enlightening
(time is often spent where you least expect it!)
Oh, how many libraries are required?
(I guess their (required) pages would be present)
