I thought about that, and didn't like changing the semantics
without changing the name.  A change from MyFree(&foo) to
MyFree(foo) would be bothersome to untangle if a change was
half-applied.

My patch removed the MyFree() function entirely.  The macro
MYFREE now calls an unmodified SaveFree().

My goal was to improve things with minimally invasive changes.

Umm.  That would confuse me.

There is already a hook to use <dmalloc.h>.  Surely they do
all this better than we do.  Would it be better to drop all
this stuff, and go back to the raw (possibly dmalloc-ified)
malloc() and free()?
