So you really need to run all 25 processes on that 8Mb box?
(For reference even the NGW100 development board comes with 16Mb RAM).
Even if you do need those all 25 processes on the 8Mb box, fixing the
memory usage of those user space hogs is lot better than trying to
save 160Kb in kernel stacks.
Last I looked, user space wasn't particularly frugal with memory usage.
