I don't think it's a good idea until THP supports shared memory.
Why? For example it would be useful for testing on machines that you
don't have root for, and that do not have a hugetlbfs mount point. For
example you could run the test case from the vhost-user's patches.
THP is not a magic wand and you can get slowness from memory
fragmentation at any time. We should not limit ourselves due to kernel
bugs.
