  In 2.x, not really.  We're looking into adding that for 3.x

  Just set it to a large number.  It's 2014, and your systems should be
massively over-provisioned with memory.  If you set

	max_request = 1000000

  Then FR won't use any more memory than with it set to "1024".  The
only difference is that when something goes wrong, it will take more
time for the server to discover that it's melting down.
