Ah, you have done this. Then I think you can merge this patch with the
dlmalloc patch and drop the README one.
Shouldn't we keep both, README and Kconfig help?
Kconfig is just a configuration tool, README is a documentation.
Sometimes it could be faster to find something in the text instead of
config.

+ This avoids zeroing memory reserved for malloc at malloc init.

+ Useful for bzip2, bmp logo.

+ When enable, make sure that calloc() is used when zeroed
