These are momstly debugging tools for developers,
a bit documented in the header files (utils.h),
although more documentation is definitely necessary.

The performance impact is close to zero(*) so there is no
need to compile it conditionally.
(*) not completely true - thread destruction still needs
to search a list _but_ this can be easily optimized if we
end up with hundreds of active threads (in which case, though,
the problem is clearly elsewhere).
