=begin
コールバックではない単なる DL::Function に対して unbind を呼ぶと
よくわからないエラーが出ます。

$ cat d11.rb

require 'dl/import'

h = DL::Handle.new
addr = h.sym('strlen')
cfunc = DL::CFunc.new(addr, DL::TYPE_INT)
func = DL::Function.new(cfunc, [DL::TYPE_VOIDP])
func.unbind

$ ruby-1.9 -v d11.rb
ruby 1.9.2dev (2009-05-16 trunk 23440) [i686-linux]
