  ****************************************************************
  Syslogd is processing the sigalrm signal in domark. The
  customer does a restart command at the same time.
  1. Restart thread does a raise SIGHUP to drive the main thread
  2. domark obtains the archive lock on the main thread
  3. The SIGHUP interrupts the domark processing.
  4. init starts running on the main thread to process the
     SIGHUP. This routine obtains the archive lock, which returns
     as lock already held-RC_LOCK_BUSY. init continues. At the
     end of init, the archive lock is released. This releases
     the lock for the main thread
  5. domark gets control back. When domark tries to release
     the archive lock, it fails with lock not held. This generates
     the abort error.

Problem conclusion

• Syslogd code has been changed to check if the lock was actually
  obtained by the request and remember that. The lock should only
  be released if the thread actually obtained the lock.
