I am a advocate of long-time eventification. We should not create a mess
in an attempt to do it quickly, but it should remain a long-term goal.
The flexibility that we gain in doing so will pay us back later.

In particular, I think it is extremely inappropriate for GDB itself to
require threads. That would, in principle, be about as bad as allowing
parts of GCC to require a working C++ compiler...
