-         "malloc-simple" was written from scratch for uClibc, and is the
-         simplest possible (and therefore smallest) malloc implementation.
-         This uses only the mmap() system call to allocation memory, and does
-         not use the brk() system call at all, making it a fine choice for
-         MMU-less systems with very limited memory.  It is rather dumb, and
-         certainly isn't the fastest.  But it is 100% standards compliant,
-         thread safe, and very small.
