It isn't needed when developing new software, but it would greatly
facilitate porting efforts of software that uses it.
Yes, I can deep-hack the software to not use that function but this
would mean a lot of changes and will be tedious to support with
future versions of the software.

I will try to use devel/libdlmalloc to see what happens, e.g. whether
there are other "unresolvable" problems with the source :)

Testing can show the presense of bugs, but not their absence.
