Use of KSM (Kernel SamePage Merging) feature in Linux kernel with LispWorks

Just curious: does anyone know if LispWorks for Linux support the KSM feature in recent linux kernels?:

   http://en.wikipedia.org/wiki/Kernel_SamePage_Merging_(KSM)  

   https://www.kernel.org/doc/Documentation/vm/ksm.txt

 According to the documentation above, an application has to advise the kernel that it is a candidate for KSM, as follows:

KSM only operates on those areas of address space which an application

has advised to be likely candidates for merging, by using the madvise(2)
system call: int madvise(addr, length, MADV_MERGEABLE).
