++  // Special handling for timeseal on FreeBSD:
++  //
++  // On FreeBSD, the games/timeseal port provides an a.out timeseal
++  // binary. However, a.out support is disabled by default on FreeBSD
++  // >= 5.x. If the a.out kernel module is not loaded, or if a.out
++  // support is not compiled into the kernel, execvp()ing timeseal
++  // will not return (because it fallbacks to the shell when execve()
++  // returns NOEXEC): eboard will not notice the failure (in
++  // PipeConnection::open()) and will therefore not fallback to a
++  // direct connection.
++  //
++  // We solve the problem by executing timeseal with execve(), which
++  // will fail if a.out support is not available. Note that unlike
++  // execvp(), execve() does not search for the program in the path,
++  // but this is not a problem since eboard uses the absolute path to
++  // timeseal.
