Splaying performed would break usual de-facto thread-safety guarantees 
for STL and
Intrusive containers (read-only access from different threads is
thread-safe).

We had the same worry about thread-safety on the self-adjusting trie in 
xpressive (xpressive/detail/utility/symbols.hpp).  Rather than remove 
the self-adjusting optimization, we decided to enable it conditionally 
when BOOST_DISABLE_THREADS is defined and exclude it otherwise.
