[bind10-dev] memory usage

My benchmarking scripts record memory usage at startup, after first 
query, and then after running queryperf.

After doing a query, b10-auth grew from

  Private  +   Shared  =  RAM used      Program 
  1.9 MiB + 528.0 KiB =   2.4 MiB      b10-auth

to:

  Private  +   Shared  =  RAM used      Program 
  2.0 MiB + 532.0 KiB =   2.5 MiB      b10-auth

Not much. And didn't grow anymore after 300,000 queries.


One report looks like:

 Private  +   Shared  =  RAM used       Program 

156.0 KiB + 940.0 KiB =   1.1 MiB       save-process-st
176.0 KiB + 960.0 KiB =   1.1 MiB       test2.sh-revise
904.0 KiB +   1.2 MiB =   2.1 MiB       bash (2)
  2.0 MiB + 532.0 KiB =   2.5 MiB       b10-auth
  5.3 MiB +   2.9 MiB =   8.2 MiB       b10-cfgmgr
  5.8 MiB +   2.9 MiB =   8.7 MiB       b10-xfrout
  6.5 MiB +   2.9 MiB =   9.4 MiB       b10-msgq
  6.6 MiB +   2.9 MiB =   9.5 MiB       bind10
  8.9 MiB +   3.6 MiB =  12.5 MiB       b10-cmdctl
 12.4 MiB +   2.9 MiB =  15.3 MiB       b10-xfrin (2)

 Private  +   Shared  =  RAM used       Program 

(Ignore the top two entries even though they are used in the totals. 
They are for the scripts that record this info and run the benchmark 
tests.)
