	23+79k -- Average resident sizes of text and data+stack.  The numbers
		  are measured in 512-byte pages.

	3+0io  -- This is the I/O charged to the process (not necessarily
		  initiated by the process).  The 3 is the total number of
		  requests, the 0 is the number of disk accesses.  The
		  difference is the number of buffer cache hits.

	2pf+0w -- The 2pf is the number of page faults that required disk I/O
		  to read the page (known in unix as major faults).  The 0w is
		  the number of times ths process was swapped to disk.
