    <para>
      libsigsegv is a library for handling page faults in user mode. A page fault
      occurs when a program tries to access to a region of memory that is
      currently not available. Catching and handling a page fault is a useful
      technique for implementing pageable virtual memory, memory-mapped access
      to persistent databases, generational garbage collectors, stack overflow
      handlers, and distributed shared memory.
