The problem is actually for someone else who does not read the list.  He
is trying to see if he can port a p-threads package to dos (class project).  
This means that things like malloc (and alot of other stuff) has to be 
guarenteed to be atomic since he will be simulating task switches.  I have not
looked into the code for the standard libraries, but I will also suggest that
to him to see if he can get by with the standard code.  But this is why we 
are overwriting some of these routines.

I guess I should have given the background.
