Have you ever managed to merge nmalloc into your local CVS repository?
IIRC I have tried a year ago but I failed.  I did not really understood how
djgpp's malloc worked and I also did not understood how nmalloc worked
so it was impossible to me to replace one with the other and I gave up.
If you have merged the code you can send me a patch and I will try the
nmalloc changes with some code of mine.
