                Prevent memory bloat on Linux with malloc_trim(0)
              
          
    The default allocator on Linux has a tendency to free unused memory less aggressively than Mac and Windows.
This creates the appearance of memory bloat.
Calling malloc_trim(0) may not prevent out of memory events of that single process, but it helps you see the real memory usage, and frees up memory for use by other processes.
