I have just mounted a revised version of nmalloc.zip, which can
supply all the features of that debug package AFAICT.  There is
still some work to be done to integrate things better, and to
resolve the semantics of the debug levels.  It includes the
provisions to alter the output file for the debug dumps discussed
here with Eli, and the use of some fields in mallocinfo to show
the count of free space blocks etc.

I think any remaining work will be largely cosmetic.  Lets have
people flog this.

The revised package is at:
