calloc vs. malloc

[DARIN JOHNSON]

There was a question on mod.unix (or something like that) about whether
interchanging malloc and calloc calls was portable.  Well I had a
problem with that just yesterday and it took quite a while to figure
out.  On the pyramid OSx it seems that if free() is called with
something calloc()'d it doesn't do what is expected.  I try to keep this
consistent, but I called free() instead of cfree() in one place, and
then later when calling malloc, it returned something still in use.
Replacing this free() with cfree() immediately solved the problem.
