Hi!

I actually usually compile without thread support. I feel it's safer and
 is more stable, and therefore prefer to compile without threads. I can
also see that my own builds, without thread support, is considerably
faster (in terms of eval/sec) than a single threaded build supporting
threads. I therefore believes the thread code adds some overhead.

The numbers in evals/sec
My own non-thread build: ~56600 eval/sec
MaX build single thread: ~48100 eval/sec

Of course I'm not convinced that the eval speed test is a fair test in
this context, however it is an indicator that there is some overhead
involved.

I can really see the benefit of having only one code to work at, but I
would still love to be able to compile without threads.
