New Revision: 274579
URL: https://svnweb.freebsd.org/changeset/base/274579

Log:
  Call sem_unlink on semaphores before attempting to create them
  
  Due to the lack of uniqueness in the semaphore name, and the fact that the
  tests don't have cleanup routines, an interrupted test can leave a semaphore
  "laying around", causing all subsequent attempts to run the test to fail
  
  I will file a NetBSD PR for this issue soon
