(bug 29747) eAccelerator shared memory caching has been removed since it is now disabled by default and is buggy. APC, XCache and WinCache are not affected.

As Brion points out in <https://bugzilla.wikimedia.org/show_bug.cgi?id=29747#c7>, the shared memory functions are very buggy. In fact, eAccelerator has disabled the shared memory functions by default for awhile now. I didn't touch APC, XCache or WinCache, but I imagine they suffer from the same problems.
