time.time() now uses clock_gettime(CLOCK_REALTIME) if available
 
clock_gettime(CLOCK_REALTIME) has a better resolution than gettimeofday().
time.time() falls back on gettimeofday() (and then on other functions) on
error.

/* "Rotating trees" (Armin Rigo)
 *
 * Google "splay trees" for the general idea.
 *
 * It's a dict-like data structure that works best when accesses are not
 * random, but follow a strong pattern.  The one implemented here is for
 * access patterns where the same small set of keys is looked up over
 * and over again, and this set of keys evolves slowly over time.
