On OS X Mavericks, the broctl top command was working, but on Yosemite
(and El Capitan), it no longer works. The reason is that the
"-stats vprvt" option of the top command always prints "N/A".
As a quick fix, I will just change "vprvt" to "mem".
This means that both memory columns in the top command output will contain the same data.
Branch "topic/dnthayer/ticket1549" in the broctl
repo contains the fix for this issue.
Would it perhaps make more sense to use rprvt on osx 10.10 and vprvt on osx < 10.10?
On OS X 10.10, the output of "rprvt" is also just "N/A".
