 /**
  * @file
  * This file provides platform-independent wrappers around threads. This is for
  * use by PPAPI wrappers and tests which need to run on multiple platforms to
  * support both trusted platforms (Windows, Mac, Linux) and untrusted (Native
  * Client). Apps that use PPAPI only with Native Client should generally use the
  * Native Client POSIX implementation instead.
  *
  * TODO(dmichael): Move this file to ppapi/c and delete this comment, if we end
  * up needing platform independent threads in PPAPI C or C++. This file was
  * written using inline functions and PPAPI naming conventions with the intent
  * of making it possible to put it in to ppapi/c. Currently, however, it's only
  * used in ppapi/tests, so is not part of the published API.
