Apache MPM beos
Summary
    This Multi-Processing Module (MPM) is the default for BeOS. It uses
    a single control process which creates threads to handle requests.
    The MaxRequestsPerThread directive sets
    the limit on the number of requests that an individual server thread
    will handle. After MaxRequestsPerThread
    requests, the thread will die. If MaxRequestsPerThread is 0, then the thread
    will never expire.
    Setting MaxRequestsPerThread to a
    non-zero limit has two beneficial effects:
    
      - it limits the amount of memory that a thread can consume
      by (accidental) memory leakage;
- by giving threads a finite lifetime, it helps reduce
      the number of threads when the server load reduces.
Note:
      For KeepAlive requests, only
      the first request is counted towards this limit. In effect, it
      changes the behavior to limit the number of connections
      per thread.
