I'm trying to get my memory management staightened out.  I
have re-segmented my program, made sure that every call
to a memory allocation routine checks for an error, put in a
Grow proc  and have allocatyed a small buffer when all attempts
to allocate memory fail.  Everything is working great, the
only problems I have are system errors when a code segment
that is needed can't be loaded into memory.

I read about a scheme you had for MacApp, where you determine the
maximum code set, and make sure there is at least this much 
memory minus the memory currently used by loaded code segments.

Question:  Do you add up the total memory used by loaded 
code segments continuously, - I guess I'm not quite sure how
this scheme works.

I would appreciate it if you could send be a little more info
on this scheme.  

Thanks
