That's an interesting question.  Thinking about that, and comparing with
GCC experience, I'd say that in general it's just extremely difficult to
get infrastructural work accomplished in a small group or small company;
you'd have to have a sufficiently large and/or well-funded group that
the time taken by infrastructure does not affect the group's overall
schedule.

I think we're in agreement on that.

I'm very glad that Red Hat can manage it! Cygnus was much more of a
hand-to-mouth operation; if contract work didn't get delivered on time,
people had to be laid off. There was VC money later, but it mostly got
swallowed up by various unprofitable initiatives.
