In article <email@example.com> you write:

This is true, and is a serious pain on systems with small address spaces.
To ensure that all processes can call mmap() (which malloc() does) on arm26,
I have to arrange that MAXTSIZ + MAXDSIZ + MAXSSIZ < 24MB, even though any
given process is unlikely to be hitting the text and data limits at the same
time. This all needs to be made rather more dynamic.
