Asking on the X.org mailing list [1] yield this information:

The X server does nothing fancy when resources such as pixmaps are deallocated.
Is up to the C library function free() to return memory to the OS. Heap
fragmentation can happen, thus preventing free() from returning memory to the
OS.

So using the X server for caching pages can indeed cause an unbounded growth of
the amount of memory asigned to the X server process.
