New Revision: 175771

URL: http://svn.digium.com/svn-view/asterisk?view=rev&rev=175771
Log:
Add the beginning of test_sched

So far, there is one test, which times how long it takes to insert a million
entries into a scheduler context using ast_sched_add().

Average running time:
  trunk:             686.7 seconds
  team/russell/heap: 2.7   seconds

Added:
    team/russell/heap/tests/test_sched.c   (with props)
