I have tested the compilation timings of my dlibs (using 'bud'), they contain lot of templates.
Compilation timings (with unittest), no run:
  V1.037: 11.33 s
  V1.038: 11.52 s
The size of the resulting exe is the same (1.887 MB).

(Without unittests the compilation is much faster, about 0.47 seconds for 1.038).
So it seems my compilation timings are grown, but not much.

I have just found out that 'bud' isn't using both cores of my CPU. Why??
