rb_define_hooked_variable creates a hooked variable.  This is how
$stdin, $stdout, $!, and other variables are implemented.  See
README.EXT for an explanation.

With:
  http://rm-f.net/~cout/code/ruby/treasures/RubyTreasures-0.4/lib/hacks/fix_trace_func.rb.html

I can write:
  ruby -rfix_trace_func -rtracer -rcrimson_profiler test.rb

and I get both tracing and profiling.  I had to use a slightly modified
profiler to get this to work, but I can't remember why at the moment.
