Alex, I found an email from you to tech 2008-07-20 that said:

With 256 color components, sizeof(gx_image_enum) == 500K . Such
large objects are allocated in separate chunks. By default, glibc
also allocates them with a separate mmap2() system call. This greatly
reduces performance of the files that have many images, for instance
a sample file from the bug 689722. 

This might be a good one to test with the latest code (without clues)
with a larger number of CLIENT colors vs. 8.71

I guess you could find which of the comparefiles slow down with rev 8863
vs. 8864 (this had image clues and 8863 had 252 components).
