[BUG][FIX] MemoryUsage-vmParamDep-huma ( [er][sm] Not a change to image )

[tomkoenig at mindspring.com]

"humasect", thanks for submitting this bug report and fix.  I'm closing
it because its a fix to a package and not to the image. I'm also
forwarding this message to the owner of the package Faried Nawaz,
requesting that he review it for possible inclusion with the next
release of Memory usage.  You might want to email him with a description
of the bug it fixes and/or a test he can use to demonstrate the
problem/fix
Faried, as you can see below, this is a one method change.
