Hi Brian,

I guess Kernel#send doesn't push a frame in 1.9, but does in 1.8.

defiant:ruby$ ruby-trunk -ve 'def foo; puts caller; end; send(:foo)'
ruby 1.9.2dev (2009-12-05 trunk 26022) [i686-linux]
-e:1:in `<main>'
defiant:ruby$ ruby-1_8 -ve 'def foo; puts caller; end; send(:foo)'
ruby 1.8.8dev (2009-12-05 revision 26022) [i686-linux]
-e:1:in `send'
-e:1

I'm not sure which behavior is reasonable, but it may be better to leave it
implementation defined.

FYI, IronRuby pushes a frame the same as 1.8, and Rubinius and JRuby doesn't.
