Thanks for these results. Yeah, the performance issues kinda sting
when I'm reminded, so we need to gradually start giving them more
attention. As Icarus Verilog gets ever more complete and bug free,
people throw ever larger designs at it. In some cases, the limiting
factor for adoption is no longer its completeness but its performance:-O

Still, there is plenty to do on many axis and I think we can stand
to attract and retain a slightly larger cadre of core developers.
This is such specialized work, though.

I cannot overstate the importance of critical sets of eyes bearing
down on things dispassionately. That's what keeps things on course.
