It seems to me that nearly everything you have been doing for the last
couple of months has been to do with shoehorning your code into a
system with too little RAM. eCos is meant to be small, but it also has
to be clean, maintainable and efficient. 

It might be time to take a step back and take a look at your problem
from a wider angel. Consider how much time you have spent so far,
consider how much more time you would need to implement SST. Consider
the maintainance of such a system. Its always difficult to get a
stable system when you have extreamly tight memory since unexpected
things will happen in the field causing hard to reporduce bugs.

Talk to your hardware people and component supply people. It might
turn out cheaper in the long run to put bigger RAMs on the board and
save a huge amount of time and money on the software side of the
