file at once, function at once, trace at once, basic block at once - just
different JIT approaches.
The bigger part we analyze at once the more information we may get for
optimization, but the slower compilation.
Just-In-Time-At-Once JITAO
It is a bit different to the thing we think of as JIT ... new names are
good if old names don't fit ...

Without the output buffering code it's a LOT more uneven, as the PHP version
is flushing every byte - approx. 6,000 such flushes.

I wanted to verify whether my gut was correct (minimal amount of output, and
stdout is in fact buffered - output shouldn't move the needle) and asked
Dmitry to rerun the C test on the same system, but this time with the output

It's been brought to my attention that some people have taken what I
said completely out of context and insinuated it as a direct insult to
you. I assure you that was not the intent (I called the benchmark
sneaky and fake, which it is).
