NOMMU: stack versus malloc?

[Denys Vlasenko]

A question to people who work with NOMMU machines:

Obviously, having small stack usage is important for
small, NOMMU machines.

However, after a certain point you cannot just eliminate
stack usage, you must move it to other storage.

For example, lineedit.c currently eats 12k+ if stack.

I can convert it into malloc use.

Question: is it better or actually worse?
Line editing is invoked repeatedly, and repeated malloc/free
of random-sized blocks can increase fragmentation
-> increase memory consumption.

Please share your experience.
