With default optimizations? Currently when -O=all is used, some methods
may take a long time to compile, but by default it should be quite fast.
Well, mini generates about 1MB of native code per second on my PIII
1.1, and 170Kbytes of IL code should be about 0.5 MB of native code,
so .5 seconds: we need to profile JIT times and improve on that.
I think doubling the JIT speed is doable, we just need some time to
spend on it...
