 * on page load, looks for a _csuid cookie on the document.  if it does
 * not exist, loads (or attempts to load) the flash service code. on a
 * successful load, uses flash to establish a definitive user id (in the
 * same namespace as clearspring cookies).  on failure, sets X[rand] as
 * the uid.  When a uid is recovered or set the first time, it's assigned
 * to the page's (domain's) cookie.  The X[rand] uid prevents future flash
 * loads from being attempted.
