New Revision: 86586
URL: http://svn.boost.org/trac/boost/changeset/86586

Log:
Thread: Added caller_context.hpp; Change executor by Executor template parameter in async; update the number of time the failing tests are run to catch all the compilers.

Added:
   trunk/boost/thread/caller_context.hpp   (contents, props changed)
