This function would be used for performance testing metric collection. 

The Chrome browser currently shows the heap contents if you take a snapshot. 
But we have no programmatic access to that type of data.

Adding a JavaScript function (along with getProfile()
https://bugs.webkit.org/show_bug.cgi?id=31133) would give an html page all the
tools necessary to collect performance data, and manipulate/collate that data.

My personal interest is in building pages that collect data and report that
data back to a server for collation/reporting.

Currently the interesting 3 core interesting metrics are time, count, and
memory usage.  we have basic timing, but we don't have a way to characterize
memory usage.  This function with getProfile() would complete the circle.  Now
the information is data, and can be collected and collated with other data from
other places.

I will be adding a bug at Firebug requesting to add a function like this there
also.
