Never trust 'em! I have a nasty overwrite problem and I start thinking that
the heap management has errors in it . (If anyone out there knows whether
this is correct, please let me know). Main point: I'm using the FreeMin
variable, and TD acts funny evaluating say "MemAvail", if FreeMin is not 
zero. I haven't at this time checked using the the internal debugger.

Very true!
