 // for getting a sample of native stack usage sizes.

 // Enabling this will cause stats to be collected and written to a log file at
 // various  instrumented points in the code. It will result in noticeable
 // performance loss. Hence, this should only be enable when you want to do
 // some stats location in your local build. This code is provided here as a
 // convenience for collecting that data. It is not meant to be enabled by
 // default on release or debug builds.
