[Fedora-directory-devel] Please Review: (450046) changelog writes can hang due to leftover semaphore

esolves: bug 450046
Bug Description: The semaphore used by the changelog can be left around
  if the server doesn't exit cleanly.  If the value happens to be at 0
  when this happens, the server will be unable to write to the changelog
  the next time it is started.

Files: see diff
Branch: HEAD
Fix Description: This fix makes the changelog code attempt to create the
  semaphore with exclusive access.  If this fails due to the semaphore
  being left around from a previous unclean exit of the server, we delete
  the semaphore and re-create it.
Platforms tested: Fedora 8 x86_64
Flag Day: no
