The malloc in glibc is not slow.  It has a number of features:
- thread safe
- allows debugging
- has internal checks

which other mallocs do not have and therefore might be faster.

But what I'm most interested in is actually data where glibc's malloc
is really slow.  Please show us an example, otherwise any such
discussion is void,
