I was probably not clear enough, but I didn't intend to insist libc
malloc performs poorly for all systems by saying "can perform poorly"
and "depending on the details".  I tried to make a general
recommendation independent of the system since different OSes have
been mentioned in this thread (at least including FreeBSD, some
versions of its libc malloc actually performs poorly).
