Userland don't tend to have source trees to build with diagnostic
flags. Maybe if distributions had two packages (prod / diag) that
could make it easier.

Run time checks are no good, too. The similar of a -vvv flag would
avoid multiple versions of the compiler installed, but that also has
performance issues, as you always have the "if (diag_level > X)"
before each assert.

As always, a trade off.

Btw, has anyone measured the delay of full assertions compared to no
assertions at all? We may be discussing over nothing...
