The culture is changing. :)

Yes, I am sure. I shipped one of my libraries to a guy who
works on various DSP chips.  The native memory allocator
on one of the DSP was very slow (some specific issues with
how the DSP addresses the memory, I don't remember the details).

This guy had to add his own new/delete operator to some of
my internal classes to get about 10 times performance improvement.

No, I really don't think that there is a hope for general purpose allocators.
