when an application executes and the system loads the shared library, it doesn't just mmap misc pages, it first read enough about the library to know what is where so that it would know what pages need to be mmapped.

It seems to me that this process could be tweaked to understand this sort of transparent compression, and uncompress the entire library (or, in most cases, find where the library has already been uncompressed to support other applications)

Even if this means that the entire library must sit in ram while it's used, this won't make it worthless (it will mean that a huge library that's not used by many apps, and the apps only use a small portion of it may not be good candidates for compression)
