 Well, you can look in bdb (common.c) and plruby but they are really badly
 written and perhaps only me can understand what they do :-)


 Basically, in rPAInit() you store the block in a thread local variable,
 something like

 rb_thread_local_aset(rb_thread_current(), rb_intern("__block__"), rb_f_lambda());

 Then when the second function is called, you retrieve the block and call
 it, something like

 VALUE block, res;
 
 block = rb_thread_local_aref(rb_thread_current(), rb_intern("_block_"));
 res = rb_funcall(block, rb_intern("call"), 1, INT2FIX(12));
