This enables Xapian::DB_DANGEROUS to support in-place updates. This can speed up the initial index and reduce I/O at the cost of preventing concurrent readers and being unsafe in the face of any abnormal terminations. This is more dangerous than --no-fsync. --no-fsync is only unsafe in the event of a power loss or kernel crash; --dangerous is unsafe even on SIGKILL.
