title: Kill a process that runs under valgrind and create summary
body: <p>I use the valgrind version 3.12.0 under x86_64 GNU/Linux. The distibuition of Linux is the Suse version 3.0.101-63-default.
  I try to terminate the valgrind process using kill pid , but the signal is ignored.
  Only when the SIGBUS signal is sent the valgrind is terminated and the summary is created.
  But I do not know if using this signal I take the correct results?
  Is any other way to terminate the valgrind?
  I use kill -9 but no summary is create at all</p>
  
  <p>Thank you</p>
