Oh, I daresay the STL sort() was *correct* from the
beginning. But when it's a) mixed in with a lot of
other flaky stuff, and b) not particularly fast in
some cases, then the decision to use it is not so obvious.

And that's a good argument for the *correctness* of such code.
But for uses which are performance-critical, I'm much
more skeptical about picking up "standard" stuff which
necessarily has to cater to the lowest common denominator,
rather than being optimized to the characteristics of your
own particular problem.

Yeah, that's one way a sort() can go wrong. The other way
is a bus error or segmentation violation ... or maybe a
pathological case that takes hours to run, or even an infinite loop. And if any of those happen,
you can bet it will be at the site of your largest
customer, right while you're negotiating a big order :-(

Trouble is that "revisiting assumptions" in 1M+ lines of
code could take years. If something shows up in profiling
or other performance analysis, then you look at it, for
sure. But otherwise it's all going to stay just the way
it is.

As for the "single-threaded" issue, I'm actively working
on ways to exploit more parallelism. But my own opinion
is that a scheme based on multiple processes (each
with their own protected address space) is likely to
yield a product-quality solution much earlier than an
approach based on multiple threads in a single address
space (which is the more conventional approach). YMMV.

Most of our code is 64bit these days - and the core code
has been 64bit since around 2000 (first on SPARC/Solaris,
then on x86_64 as soon as that became available).
I don't think it made much difference to any of the
design decisions though.

Yes you are. You're relying on the undefined behavior of
how much memory malloc() will give you, on a particular
platform, with other processes running, before it craps
out and returns NULL. Which depends on the allocation
algorithm, the pattern of allocations, how much swap space
the machine is configured with, and what other processes
are running. In my trivial example, the answer is
that malloc() is going to crap out right away. But *no*
implementation actually defines the behavior in detail -
fragmentation is too complex, the OS environment is too
complex.

Some aspects of the undefined behavior were a pain that
we had to work around; other aspects of the undefined
behavior were helpful, and we started to rely on them.

There you go, that's just the kind of "undefined behavior"
of malloc that I'm talking about.

Maybe it does, maybe it doesn't. The dirty secret about
multi-core and multi-socket machines with caches is that
your threaded program is going to spend a whole lot of
time moving cache lines between the different caches.
It's not completely obvious that moving data explicitly
and in advance will end up costing you a lot more than
having it happen implicitly on demand. And the implicit
case is *definitely* going to be harder to understand
(because the data movement operations that take the time
are not apparent in the source code).
