title: dump valgrind data
body: <p>I am using valgrind on a program which runs an infinite loop.</p>
  
  <p>As memcheck displays the memory leaks after the end of the program, but as my program has infinite loop it will never end. </p>
  
  <p>So is there any way i can forcefully dump the data from valgrind time to time.</p>
  
  <p>Thanks</p>
