  160Mb does sound like a lot.

  The 380 bytes "definitely lost" is from libltdl.  It contributed
almost nothing to the 160M total memory used by the server.

  If valgrind doesn't say that the memory is lost, then the memory is
very likely still being used.  i.e. It's likely needed for something.
