If i remember correctly, it think it was once said that the linux
version of jffs2 has a thread which does a garbage collect every so
often and that eCos does not have such a thread. eCos only does a
garbage collect when it really must do. 

Maybe if you implement the garbage collect thread you can reduce your
RAM usage.
