Comment(by blb@…):

 To compare against my earlier results, quickindex-array.diff shows:
 {{{
 $ time port-test -dy install gnome > gnome_patch2.txt 2>&1

 real    0m26.863s
 user    0m18.970s
 sys     0m6.854s
 }}}
 using a max of 340M of memory.  So faster than my update without the
 memory cost.  Note that this was after the PortIndex.quick file had
 already been generated, though that definitely doesn't take much time
 either.
